Persona Based Interviewing

Why you may need to do some actual testing in the interview for your next testing role

Interview

 

When I was starting to think about writing some posts to help out those who are either recruiting testers (see here for my first post), or for testers looking for new roles, the obvious first post was going to be around interviews. Interviews are scary, interviews need preparation, etc.

But to be honest, there is already so much available on the web that’ll teach you the basics, that I’d be re-inventing the wheel.

This is the second post in a series on finding a job within testing – the first one is Starting a New Job In Testing which you can also read on this site.

Basic interviewing techniques

If you need some help on basic interviewing techniques then I’d recommend spending some time on Ministry of Testing, looking at the recruitment resource section. What I want to discuss in this post is an interviewing technique we are using where I work, in order to help us recruit testers. It’s not new but it’s also not typical, and so hopefully it helps you.

 

A typical interview

A typical interview has a set of questions, and sometimes a script to follow. While the questions may not be written down, an experienced interviewer typically has a number of questions in their head that they can tailor to the interview situation, and use to steer the conversation in a particular direction. There may be a formal test, or the interview may just be conducted verbally.

Simply asking someone questions about testing, and gauging their responses, is one way of understanding in more detail what they know. You can also find out more about who they are, and what they can bring to the company. While we are following this approach, we’re also doing things a little differently.

 

Persona based interviewing

In a persona based interview, each of the interviewers play out part of a task based story, which the candidate is also a part of. One of more scenario’s are played out, normally based around a task that the candidate would typically face if they were successful in joining the company. The interviewers take different persona’s, each playing the part of a role or person that the candidate would need to interact with, in order to successfully pass the task that they are set. In this way the interviewers can understand how the candidate approaches particular tasks, how they solve problems, and how they interact with others.

For our interviewers for mobile test positions we typically play out some scenario’s based around testing our applications on real hardware. I won’t go into too much detail, for obvious reasons, but the candidate receives a certain testing task, and then is expected to start testing and exploring the application in order to successfully find bugs within it.

We play the parts of other people in the story. These could be the Product Owner deciding on re-prioritisation, other testers being able to offer advice, a developer being difficult or helpful, or even a senior manager wanting to know the progress of a testing task. As we go through we throw in these sorts of requests, and other changes to the scenario, in order to see how the tester works when requirements change and the pressure mounts.

Attempting to complete the tasks without interacting with the other roles within the scenario is very difficult and we are looking as much towards how and when the candidate asks for help, as we are to the testing skills that they show.

After the scenario’s are complete then we discuss with the candidate how they think the scenario’s went, what they thought went well and what they would do differently if faced with them again.

 

Is persona based interviewing useful for test roles?

We think it is. Mainly because:

 

It gives us a better idea of how the candidate thinks, and how they approach a testing problem

I’m a firm believer in context-driven testing and Rapid Software Testing in particular, as is the company I work for. To me, being able to observe how someone approaches a testing task, who they communicate with, and what questions they ask is very important. Being able to get an understanding of how they change their approach based upon the context is also much easier within the scenarios. Using persona based interviewing I get to discover more about ‘how they tick’ rather than what testing terms they can remember, or how much of their career story they can tell.

 

We get to see a candidates real, practical skills

By giving the candidates tasks based around testing our live applications, usually on an iPhone or iPad, we give the candidates an opportunity to demonstrate the real, practical skills that they have. We encourage the candidates to talk us through what they are doing and give them the opportunity to demonstrate what they know. Being able to demonstrate ability also puts people more at ease and we get to see what they can really do.

 

It focuses on critical assessment and improvement

By having a de-brief or lessons learnt session after the scenario’s have played out, we also get to see how a candidate critically assesses themselves, and discover what they would do differently given another chance. Making mistakes is human but learning from them is the important thing, and I don’t expect testers in my teams to get everything right first time. However I do expect them to be able to recognise ways in which they can improve.

 

It’s more fun than just answering questions

It’s certainly more fun for the interviewers, and hopefully it’s also a bit more fun for the candidate (as much as interviews can be anyway). Asking questions isn’t much fun, and only being able to show your skills in simple answers, is not the best way to spend your time. Demonstration of skills tests how a candidate works not what they can remember.

So, why not try persona based interviewing next time you are recruiting for testers. It can be a great way of finding really good people who you can have confidence will do a good job.

 

The next post in the series will be about C.V.’s, and what you need to highlight in order to get noticed.

Starting a New Job in Testing

4 Comments
Image

Thing have been a bit quiet around here. Maybe you’ve noticed it. Maybe you’ve only came to this blog for the first time, from a link from Google or Bing, in which case welcome, and do note the gap in posts. I’ve been busy.

Primarily this has been because I’ve been searching for, and then settling into, a new job in a new company. Starting a new job isn’t easy, be it in testing or any other field, and it’s what you do in the first few months in a new company that can really affect how the rest of your time there goes. Those relationships you make early on, and how you are seen by others matter. It matters a lot.

So, while things are fresh in my mind, here’s some handy hints on what you should consider when starting somewhere new. I’ll be sharing further articles about recruitment, job searching and C.V.’s over the forthcoming months.

All presented with a software testing view.

Talk to people

Probably the most important thing you can do when you start, especially in a testing role. Being a good communicator, with the ability to get on with as many people as possible is very important as a tester. Spend your time searching out the important people, introduce yourself, and find out more about them. Ask them about the company, ask them about how you can work together, and find out what they think about how the company does testing. Those relationships you make early on affect how people see you for a long time. Sure, you won’t be able to remember all their names, but make sure they remember yours. And yes, this does mean talking to more than just testers 🙂

 

Ask Questions. A lot of questions

Testing is all about questioning a product in order to evaluate it, right? Take the same approach when you start a new job. Ask everything you can think of, no question is too stupid to ask if you don’t know the answer. Often, so much information in a company, is un-documented, and you want to make sure that you can understand the bigger picture, as well as just knowing enough to do your role. As testers we need as broad a view as possible in order to work effectively so make sure that you learn by questioning, and continue to do so. It takes time to settle into a new job but the more questions you ask then the quicker you should be able to feel like you understand company and your role within it. Don’t sit there, feeling blocked because you don’t feel like you can ask something.

 

Be nice

First impressions count. When you first start you meet a lot of people. Every time you meet someone new then that’s a new first impression. Always remember to be nice. Even if you are really an evil tester 🙂

 

Consider what you are bring to the company

They decided to employ you, there must be a reason, right? 🙂 Remember that you have good, and relevant, experience that you can bring. It’s easy when you first start, to just spend your time learning the company and your new role. But do not forget that your experience from outside the company could be really useful. Maybe your old company did it’s test automation a particular way or maybe you can see the new company works in a way you helped improve in an old role. It’s often new starters who are in the best position to see improvement areas. Don’t just accept that ‘this is the way its done round here’, and don’t feel afraid to speak up.

 

Ask for feedback

It can be really easy when you start somewhere new to just go into things head down and try and pick everything up at once. Remember that you need to pause and ask for feedback. Make sure that you question your own understanding of things, as you learn them, and regularly ask for feedback from those you work with.

 

Don’t forget to continue focusing outwards as well

When you start at a new company it can be really easy to spend all your time learning your new role. After all, there is a lot to pick up and a lot to learn. It is tiring, but don’t forget what you did before. Since you are reading this then I assume you read software testing blogs at least. Keep active in the testing community and keep learning. That way you can bring not only new ideas from your previous job, but also new ideas from the whole testing community.

 

Enjoy it

It takes a lot of effort when you start a new job. There is a lot to learn and a lot of people to meet. Focus on what attracted you to the new job and don’t forget to enjoy it 🙂

I’ll Be a Panelist at the Next Generation Testing Conference on 6th December

1 Comment

I’m excited to be able to announce that I’ll be a panelist at the Next Generation Testing Conference which is on Thursday 6th December in London.

The conference is in its seventh year and is continuing with the  format that was trialed at the last conference in May, with more emphasis on panels and discussions, together with case studies. This should hopefully mean that there’s some great audience participation and discussion on software testing.

I’ll be on two different panels during the day – “Retrospective on 2012” and “Looking Forward to 2013” We’ll be debating various topics including:

  • What have we learned in 2012?
  • TestDevOps – what does it mean to you?
  • Continuous Integration and Continuous Delivery – lessons learned
  • Mind Map techniques that work with Agile
  • Advances in risk-based testing
  • Changes in approach for testing cloud based solutions and mobile applications
  • The rise of TestOps
  • Innovation/renovation
  • What is the next big thing?
  • “Prespective” of 2013

Others presenting or as panelists at the event include Paul Gerrard, Julian Harty, Steve Tulk and Niels Malotaux.

It’s sure to be a great event, as the last one was. Hope to see you there. You can find out more about the event at http://next-generation-testing.com/

A Good Test Case Is?

1 Comment

I’ve recently been reading through my ISEB Practitioner notes, which I got when attending a course organised by Grove Consultants a few years back, as I mentioned in my previous post. It’s got me thinking about test cases, and in particular the four criteria of a good test case. Having attended both Rapid Software Testing and Rapid Test Management recently, and having rolled out an Exploratory and Session Based Test Strategy in my teams then it’s caused me to question again the validity of test cases and the need for them.

So, to a good test case. Reading my notes, a good test case is, in no particular order, apparently:

1. Exemplary.
2. Evolvable.
3. Economic.
4. Effective.

Straight from the ISTQB/ ISEB of course. But not without merit. Are these still relevant?

Exemplary

Good test cases can test more than one condition at the same time. This is one good reason for taking the time to design test cases in the first place. Just writing test cases because “it’s the done thing” or “because the policy says so” is time wasting, but designing them so that when the testing is carried out it is done so in the most efficient way requires exemplary test cases and can add value. It is also the case that test cases are shared and it’s difficult, especially in large organisations, to ensure that all testers have the same basic level of ability. Having test cases can help.

Evolvable

From a contextual point of view perhaps a good test case is not written down at all but merely in the testers head, and driving the testing into particular areas that the tester feels are worthy of time and effort. Cases where the software is the specification are becoming increasingly common; in-sufficient or non-existent requirements documentation which requires the tester to apply their previous knowledge of the system under test in order to effectively test it. Clearly in this case, if documented test cases are required then they will be need to evolve. As Rapid Software Testing mentions “How do you invent the right tests at the right time – evolve them with an exploratory strategy”.

Economic

Time is money and often in testing we have little time and sometimes little money. So using that time and that money in the most efficient way means we minimise the economic impact. Of course, sometimes the best way to get maximum value is to have a purely exploratory approach and spend more of the time and money with the software in hand. A choice which is key to a good test strategy and highly dependant on the industry area one is testing within.

Effective

Clearly a good test cases should be effective. We are not in the business of wasting time, particularly when time is precious as it often is in testing projects.

 

I’d argue that the definitions given in ISEB/ ISTQB are still relevant and can be a good guide as to what is required of a test case. In a lot of industries test cases are still very much required and, particularly where there is strict regulation such as in areas of financial software and even in mobile software. The ability to write a good test case is a skill which should not be forgotten.

Seeing the Wood For the Trees

I’ve recently been reading through my ISEB Practitioner notes, which I got when attending a course organised by Grove Consultants a few years back.

Don’t switch off yet. I know I mentioned ISEB. So before I go further, it’s worth stating my thoughts on the whole ISEB/ISTQB debate. I summed up my frustrations in a previous blog post; the fact that in the UK having ISTQB certification is practically the only way to get past the recruiters gate, but I also feel that there is some merit to the courses if taught properly, and followed up with a context driven approach such as Rapid Software Testing.

Reading back through my notes from Grove I can now see that this is what they were trying to work towards. At the time I had no idea how important the context driven school of testing was, nor the work of James Bach, Michael Bolton, Cem Kaner and others. But looking in the notes, the names are there. The techniques, albeit in nowhere near the detail that James or Michael teach in class of course, were hinted at and some approaches, particularly Exploratory Testing, are mentioned in some detail. Some slides are directly referenced from James and Michael’s work.

Unfortunately, due to the need to pass the exam, and with these areas being marked as ‘not exam’ then I didn’t pay them the attention that they warranted, and so it took a few more years to discover how and why the context driven approach can be so powerful. Which maybe shows the true problem with ISEB/ ISTQB certification after all.

Time To Start Speaking In Public

Leave a comment

Yesterday I attended the Next Generation Testing Conference in London. Whilst on the face of it this is nothing new, I’ve been to conferences before, this time I was presenting and also took part in a panel session. This was something new for me; I’ve often presented within Nokia, and have run a number of training courses internally, but never to paying public so the pressure was on to make sure that things went well.

The Next Generation Testing Conference is not one that I had been to before, and this time the organisers UNICOM were also trying out a new format, with more emphasis on expert panel sessions, all focused around three main topics:

  • Testing Today – What are the main challenges?
  • New Tools and Techniques
  • All about Agile

The day started with coffee, introduction and some brief networking; there were people from many different areas of testing in attendance, ranging from finance to TV, all with testing and Agile as the common denominator. Then it was straight into a case study presentation about automated testing from Bertrand Meyer. He made some interesting points, some I agreed with and some I did not, and my reaction seemed to mirror the general reaction from others in the audience, as we spoke more about what we’d seen in the first coffee break.

Then it was over to my part. Dr Richard Sykes was doing a great job as facilitator and the first panel session, “Testing Today – What are the main challenges?”, with myself, Tony Bruce and Chris Ambler started. We got some good questions from the audience and some good discussions going, both with the audience and also between ourselves. The panel format worked well and made the event seem less formal than others that I have attended.

Panel session over then it was straight into my keynote “Mobile Testing, That’s Just a Smaller Screen, Right?” I spoke for about 40 minutes about mobile testing, giving the audience an overview of the mobile world as it stands today, pointing out the main challenges and areas to focus upon. This was followed by a quick overview of tools and techniques to use, and answers to questions such as “Which devices should I test on?” and “Where do I get all my devices from?” The time went quickly, it was good fun to get back to doing some presenting, and my part seemed to be well received from the feedback I got during the lunch interval. Plus some inevitable requests to help fix people’s phones 🙂

After lunch it was then time to relax and enjoy the rest of the conference. Two more panel sessions, “New Tools and Techniques” and “All about Agile” were well received and the participants were well versed in their subject areas, and able to give some great examples and tips. Sandwiched between the two panels was a bold, and very good, presentation from Colin Weaver at DB Consulting, on “10 Key Behaviours for a Successful Agile Tester”. This prompted a lot of debate in the room, regarding which behaviours were and were not applicable or specific to Agile, and which were in fact not needed at all. Healthy debate continued for the rest of the afternoon until wrap-up.

Overall it was great to be involved in a conference like this one, and I think the panel format worked very well. Thanks to UNICOM for inviting me to speak, and to all those who spoke as well. I hope this can be the start of more experience like this and I’m certainly now on the look out for more opportunities to present or run tutorials and workshops.

More Experiences of Rapid Test Management

Leave a comment

If you remember from the last post, I recently attended Rapid Test Management, taught by Michael Bolton in London. For a general overview and what happened in the first day then take a look at the previous post. As before, the following caveat applies:

Caveat – this is not a list of exactly what happens in a Rapid Test Management class, nor is it a list of exercises and course material. You won’t become good at Rapid Test Management by reading this post. Sometimes I forget things. If you really want to know about Rapid Test Management then you need to sign up for the class. It will be money well spent and this post will tell you a little about what might happen if you do take the class.

We started day two talking about test strategy and how one might incorporate Rapid Software Testing into a test strategy. The Heuristic Test Strategy model was introduced and we studied this in some detail, and followed it up with an exercise to define a strategy for a smartphone. I was happy with the choice of product under test, given my background then it made it easier to take into account my domain knowledge, and so our group could come up with a large number of options to consider. Equally interesting was what other groups had come up with and it was very interesting to see how each group had approached the problem differently and come up with different solutions. This goes to show that diversity in teams and experience is very important in testing.

Back on day 1 we had produced a list of areas that we, as a group, wanted the class to be focused upon and the major areas that so far had not been covered were risk and test coverage. As usual, Michael had some great experiences to share and course material to cover the risk areas and the details of risk based testing. In fact, the amount of class material was another one of the great things about this class – you get a lot, far more than you can look at or can be taught in the class itself. Together with some useful testing tools and also some more exercises and demo’s, this gives a great set of material to use afterwards. Continual learning is important and so to gain access to all the notes, examples and slides is just the start.

Day 2 was concluded with a look at test coverage and ways to visualise test coverage. Rapid Software Testing provides you with some great ways to do this, from the simple to the more complex. It got me thinking about how I might incorporate this into the Kanban project management processes that my own team use to manage our work.

So, should you sign-up for the class? You bet’cha. Rapid Test Management is a class that you should attend. If you want it to, and you take the time to study all the information and material that you receive, then it will make you a better tester and it will make you a better test manager. I’m on the way; I’m just beginning to take on-board all I’ve learnt and to read through the material we didn’t cover in class, but with everything I read I’m confident that it’s improving my skills.

Caveat – this is not a list of exactly what happens in a Rapid Test Management class, nor is it a list of exercises and course material.

It will be money well spent and this post will tell you a little about what might happen if you do take the class.

Last week I had the opportunity to attend one of the first Rapid Test Management classes, and certainly the first one to have been run in the UK. It was a great experience and the beginning of a lot more learning. There were attendees from a number of different areas of software testing and together I think we formed a very effective group, learning from each other and sharing experiences.

Rapid Test Management follows on from the Rapid Software Testing class that James Bach and Michael Bolton teach. I’d attended James’ class in Cambridge at the beginning of March and so, with the class material and my ideas rolling around in my head, I pitched up at the Hilton hotel in leafy Kensington (well almost Shepherds Bush actually) for two days of intensive learning from Michael.

Rapid Software Testing is a context driven technique, intended to enable testers to excel at our chosen craft. Since it focuses on testing as a craft itself, instead of merely on the production of test cases and then their use for testing (or it could be argued merely for checking) then this does put some questions in mind when considering how best to manage it. By way of some preparation, I noted down some of the questions that I had:

  • How can I best manage each testers time when adopting a Rapid Testing based strategy.
  • How does estimation fit in with the Rapid Software Testing ethos?
  • How can I sell the idea of Rapid Software Testing not only to those within my team who may be sceptical, but more importantly to those who manage me, who are most likely not only sceptical but also less knowledgeable about software testing in general?

Day 1

The class was split into two days, the first morning focused mostly on refreshing understanding of Rapid Software Testing and ensuring that, as a group, we had effectively collected our own desired outcomes from the class. It was good to spend some time going back over the methodology itself even though I had learnt it very recently. It was great that Michael seemed happy to tailor the class to the audience in any way that was necessary, taking a lot of time to ensure that everyone’s opinion could be heard.

What I found great about this class, and the RST course, are the little nuggets of information, stories and quotes that James and Michael pass on. Looking back through my notes from this class I find that’s what I mostly write down, quotes like:

 “Quality is value to someone who matters”

“Testers tell stories about products”

We also spoke in depth about the testers Elevator Pitch, that two minutes where you have to explain what testing is all about. Being able to explain and justify the role of testers and test teams is a critical skill and Rapid Software Testing gives you that skill.

When implementing any changes, such as introducing Rapid Test Management for example, then it’s critical to take into account the existing knowledge and processes that are already in use. Michael stressed the importance of ensuring that it’s not only the documented processes that are considered; in fact it’s the informal processes that are far more important to understand. He spoke about tacit vs explicit knowledge and how it is important for managers to be aware of the tacit knowledge in a test team and not merely the explicit knowledge.

We then took a look at how to put together a good team and how to train a new tester who was coming onto the team, through guidance and suitable heuristics. It was great to discuss with the others in the class about the issues they had faced when coming into a new team or bringing new team members in and also what had gone well. Ensuring that people are trained in a fault tolerant environment and gradually introduced to new tasks may seem fairly obvious stuff but it’s  often over-looked, as is the need to ensure that feedback is both given and asked for from new team members.

Day 1 concluded with a look at metrics and how important they really are, v.s. how important most organisations seem to think they are. Michael pointed us towards Cem Kaner and Walter Bond’s paper Software Engineering Metrics: What Do They Measure and How Do We Know which I would definitely recommend reading.

Reversal?

2 Comments

I’ve been studying recently for a Chartered Management Institute Level 5 qualification. As my time in my current role comes to an end then it’s important to make sure that the management activities and experience that I have built up in my 9 years at Nokia is accurately reflected on my C.V. in a way that future recruiters will recognise. But the good thing is that through the course I have also been introduced to some techniques which are new to me, are useful for the future and can be applied to the software testing field as much as anywhere else.

Recently I learnt about a problem solving technique called reversal. It’s nothing new I know, but it appealed to my testers mind. It appealed to the part of me who wants to see how things could be made worse, how faults could be found, and how increased risk could be identified. The sort of mind-set that can equally be applied to software testing situations.

The reversals technique is a basic information based decision making technique. It breaks problem solving down into the following activities:

Identify the situation under study.

  • Consider how the situation could be made worse.
  • Create as many options as possible which will make the situation worse.
  • Reverse the options to identify ways of improving the situation.

As an example, consider a situation where a lack of road capacity has been identified. Using the technique, one could come up with options such as:

  • Close all the motorways.
  • Discourage homeworking.
  • Close alternative transport mechanisms.

Then by reversing these, one could come up with solutions which could improve the situation:

  • Build more motorways.
  • Encourage homeworking.
  • Build more alternative transport mechanisms.

A simple example I know, but you get the picture.

I think we can apply this to software testing as well. I recently read the blog post by Ilari Henrik Aegerter about What you Can Do if your Brain just Refuses to Understand and one addition I’d make to his list would be to consider some problem solving techniques. I find they help me unlock the locked parts of my brain. Reversal is one such technique.

Consider the situation where you know a bug exists but you just cannot reach the root cause. If you’ve run out of options when it comes to reproducing a bug, consider reversal. Think about what really will not cause the bug to happen, what combination of key presses or code paths that won’t help. Then reverse them. Consider a situation where you need to load test a system. What could you do that would actually make it faster? Then reverse them.

Hopefully it gives you a new perspective and another tool in the belt.
