How to ace a quality assurance interview

Screening, behavioral, and technical questions–all of them wait for you in a typical interview for a quality assurance position. Ready to learn how to answer these questions?

Before studying the questions and answers, you should ensure that you understand the basics of the interview for QA jobs.

In everything you say and do in the meeting with the employer, you should demonstrate your precision, your attention to detail, and your strong interest in quality and in discipline on the workplace.

Showing the right personality and attitude is crucial. Unless you do that, they will not hire you. Let’s have a look at the questions.


Technical questions

Question 1.: Define a typical quality assurance process.

Answer: The main steps depend on the object of testing and the goal of testing. However, we can outline some steps that apply to most QA processes:

  • test of quality of the processes
  • report of mistakes
  • design of improvements
  • implementation of improvements
  • new testing of quality
  • ….

Question 2: What is six sigma level of quality?

Answer: Six sigma level of quality means that the probability of failure is confined to six sds on the normal distribution function. In practice it means that the chance of failure is less than 1:1,000,000.


Question 3: What is ISO 17025?

Answer: It is (it was) an international standard that clarifies ten technical and fifteen managerial requirements for the competence of carrying out quality tests. It used the be the standard for the industry.


Question 4: What characterize a great QA engineer from your point of view?

Answer: A great QA engineer should be able to verify, detect, prevent and reflect on the level of quality of the object they are testing. They should have attention to detail, ability to focus on their job, they should think systematically, and have good communication skills.


Question 5: Which testing types do you know?

  • Acceptance testing
  • Ad Hoc Testing
  • Software testing
  • Compatibility testing
  • Cloud testing
  • Black box testing
  • Risk Based testing
  • Requirements testing

You should mention only the types of testing you understand, and can elaborate on, explaining their advantages and disadvantages when compared to other testing methods.


Question 6: How would you test a vending machine?

Answer: This is a simple case study, and they can actually use another object, instead of a vending machine–can be more simple, such as a pen, and more complex, such as a car. What they try to see is whether you can systematically describe a testing of something new to you, whether you can design the process from scratch…


Screening and behavioral questions

The HR managers asses much more than your technical skills in an interview.

They try to understand your personality,  your motivation for the job, as well as your behavior in various situations that happen commonly on a workplace.

On the top of that, they are interested in your attitude to other people, your colleagues and customers. All of these things are important for them to know, if they are to make a right decision about hiring you.

You can expect to get at least some of the following questions in your interview:

  • Why did you decide to study quality assurance? (Speak about the inner technician that you carry within. Mention your quest for perfection. Explain how you have always spotted defects in your life, and strived to remedy them.)
  • This is a repetitive job. What would motivate you to do it well every day? (You can talk about a good collective of people, about a sense of responsibility, or about anything else that motivates you in job. Alternatively you can say that you need a job, and will be motivated to work hard simply to not lose your only stream of income.)
  • Tell me something about your former colleagues (bosses). (Try to speak positive. Show them that you can appreciate other people and recognize their qualities. Try to make an impression that it is a pleasure to work with you, and that you always try your best to maintain good relationship with your colleagues.)
  • Describe a conflict you had with a colleague in the past. (Talk about a constructive conflict, one that made sense. For example when you discussed a defect, and had a different opinion on the reason or remedy, or form of testing. Such a conflict can eventually result in an improvement of a production or testing process. What is more, try to ensure the interviewers that you do your best to avoid useless conflicts with colleagues.)
  • Describe a situation when you struggled to get your message over talking to one of your subordinates. (People of all intelligence levels work in the factories, and it is not always easy to convey a message, especially if it is highly technical, or if the person is not interested. Show the interviewers that you use all possible means of explaining things in a simple way, such as pictures, demonstration, illustrated charts, etc.)
  • Describe a goal you achieved lately, either in personal or professional life.
  • Why do you want to work for us, and not for one of our competitors? (This is your chances to show them that you did your homework, that you clearly know why you want to work for them. Look for something unique, something you can compliment them for. For example, the company may be famous with a great working environment. Or they may occupy the prime position on the market with their products. Pick something that distinguishes them from their competitors, and claim it as your reason for application. And if you can find nothing else, you can just say that you have a good traffic connection with the place, or prefer their brand to the rest of the pack.
  • What are your salary expectations? (Do your research. Check how much do quality assurance workers earn in your city/country. You can find these numbers online, just google it. Then try to be realistic in your expectations, and stress that the salary is not the deciding factor for you.
  • Describe a situation when you were under pressure in work.
  • Why should we hire you? (Repeat your strengths, and try to convince them about the value you can bring to their company. They will pay you a good salary each month, and they need to have a good reason for doing that. Be confident. Tell them how they will benefit from having you in their team!
