How to ace a quality assurance interview

If you want to get a job of a quality assurance manager (or engineer), you will have to deal with a set of screening, behavioral, and technical (job-specific) questions.

They may invite you for a single interview session, or they can divide  the process to two or three interviews (one with an HR generalist, another one with the executive from the company), but the questions remain the same.


Technical (job-specific questions)

Question 1.: Define a typical quality assurance process.
Answer: The main steps depend on the object of testing and 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.

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 (their advantages and disadvantages).

Question 6: How would you test a vending machine?

Screening and behavioral questions

The HR managers asses much more than just 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 in a job of a quality assurance manager. You can expect to get at least some of the following questions:

  • Why did you decide to study quality assurance?
  • This is a repetitive job. What would motivate you to do it well every day?
  • Tell me something about your former colleagues (bosses).
  • Describe a conflict you had with a colleague in the past.
  • Describe a situation when you struggled to get your message over talking to one of your subordinates.
  • 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?
  • What are your salary expectations?
  • Describe a situation when you were under pressure in work.
  • Why should we hire you?
