15 Quality Assurance Engineer Interview Questions and Answers

What is the difference between quality assurance, quality control, and testing?

This question helps you evaluate whether the candidate understands some of the basic technical terms in the quality assurance industry. The ideal candidate would be able to define each term and differentiate between them clearly. What to look for in the candidate's answer:

  • Mastery of the definitions
  • Ability to differentiate the terms
  • Knowledge of how the terms apply in the quality assurance industry

Example:

“Quality assurance is monitoring the testing process, quality control ensures that there are no errors, and testing is how you check for errors and the quality of the product.”

What would you include in a quality assurance testing document?

Understanding the candidate's experience with testing documents is crucial since it's an integral part of quality assurance. If they have experience with testing documents, they can tell you what they might include in one. For candidates who don't have experience with testing documents, they can describe what they are and their importance in quality assurance. A good response includes:

  • A description of what a quality assurance document is
  • The importance of testing documents in quality assurance
  • The candidate's experience with testing documents

Example:

"Testing documents are developed before or during software testing. When creating a testing document, I would include the testing effort needed, requirement tracking, and the test coverage to ensure the highest quality product is created."

Would you say public speaking is an important skill to have as a quality assurance engineer? If yes, why?

This question informs you on whether the candidate understands the importance of public speaking in quality assurance. It also helps you discover whether the candidate clearly understands the duties associated with their role. An ideal candidate would probably cite instances when their public speaking skills helped them perform their duties effectively. What to look for in an answer:

  • Knowledge of a quality assurance engineer's responsibilities 
  • An explanation of how public speaking applies in quality assurance
  • Instances when the candidate used public speaking in their job

Example:

"I believe public speaking skills are an important tool for a quality assurance engineer. In my previous job as a QA engineer, I used my public speaking skills to present test reports and analysis to my colleagues, which I had to ensure were clear and concise."

What is the greatest challenge you faced as a QA engineer, and how did you overcome it?

In their line of work, QA engineers faced many challenges. You want to ensure that the candidate you select for the position can handle problems efficiently and calmly. Understanding how they overcame their greatest challenge will likely give insight into their problem-solving skills and creativity. A satisfactory response demonstrates:

  • Familiarity with common QA problems 
  • An incident where they faced a great challenge
  • How they overcame the challenge

Example:

"In my previous job, we had an issue with the testing software. I could tell that the results it gave were inaccurate since they were far past the expected values. After examining the software, the technicians reported everything seemed fine and that the results were probably accurate. However, my time as a QA engineer taught me to predict results, and after more testing, we found that the software had a problem."

What is a test strategy?

Understanding the meaning of essential technical terms like 'test strategy' in QA assures you that the candidate is knowledgeable in the field. People often confuse 'test strategy' with 'test plan.' Listen for whether the candidate describes one instead of the other. A good response includes:

  • Familiarity with the term
  • An understanding of how the term is applied in QA
  • An accurate definition that doesn't overlap with the test plan's description 

Example:

"The test strategy outlines the plan for the software's testing stage. It covers the whole testing phase of development, unlike the test plan, which describes only one specific test. The test strategy entails a description of test groups."

How do you prioritise when you have several tasks to accomplish at once?

Sometimes workflow may be inconsistent for QA engineers, and several tests could be sent in at once that require attention. In such cases, prioritization, excellent time management, and organisation are important in ensuring that all the tests are attended to in good time. The ideal candidate could draft a work plan while putting all essential factors into consideration. What to look for in an answer:

  • A clear and efficient system for prioritizing tasks
  • Excellent organisational skills
  • Impressive time management skills

Example:

"Whenever we had a backlog of work in my previous job, I would identify which tasks had the shortest deadline and the expected amount of time to complete each test. I also grouped similar tasks together so they could be done within the same period, as it would take a shorter time. I focused on tests that were more urgent and completed them first."

Name some tools used in automation by a tester.

In quality assurance, several tools are used by testers to implement software. It would be wise to hire a candidate who understands the different tools and their uses. A good response includes:

  • Knowledge of common automation tools
  • How the named tools are used in QA
  • Experience with a variety of tools

Example:

"I've used Selenium for website testing before, and it was quite easy to use. I would recommend RavSTA and TANorex, which are good for beginners since they don't need coding.”

What are the duties of a QA engineer?

This question helps you to know whether the candidate understands their key responsibilities and has experience as a QA engineer. The ideal candidate can list both common QA duties and others they learned while on the job. What to look for in the candidate's response to this question: 

  • Duties that are specific to a QA engineer
  • Knowledge of the field
  • Experience performing QA engineering duties

Example:

“The duties of a QA engineer include troubleshooting the product in use and rectifying problematic areas using the troubleshooting process. My time as a QA engineer taught me that there were several additional tasks I was expected to perform that I didn't know about, but I was quick to learn them and eventually excelled in my role.”

What skills do you think are crucial for every QA engineer?

This question informs you whether the candidate understands the role they're expected to play and the necessary skills to accomplish their tasks. It would be wise to choose a candidate who can list skills that are specific to the position. Also, the candidate can state how they used their skills as a QA engineer. A good answer includes:

  • Skills specific to QA engineers
  • Experience using those skills in QA
  • A clear understanding of the responsibilities of a QA engineer

Example:

"I believe some of the most important skills in QA engineering are problem-solving, critical thinking, excellent verbal and written communication, good documentation skills, time management, and technical engineering skills. I improved on some of my skills like critical thinking and documentation while on the job and realised how much more efficient I became after my improvement."

Differentiate between verification and validation in QA.

Verification and validation are important processes in QA. This is a technical question that will provide further insight into the extent of the candidate's QA knowledge. You may want to hire a candidate who can accurately distinguish between the two and explain their experience with either. What to look for in a good answer:

  • A clear distinction of the terms
  • How both processes apply in QA
  • Experience with either or both processes

Example:

"Verification occurs in the software developmental stage in assurance while validation only occurs when a software is fully complete. In my previous job, I was involved in both processes to ensure the software complied with the stated requirements."

Which software do you prefer as a QA engineer and why?

This question informs you of the candidate's software preferences and thus their specialties in QA engineering. It also gives you insight into whether their specialties match your company's preferred software. The ideal candidate would explain why they prefer their chosen software, and you can decide whether their choice is well-informed. What to look for in a satisfactory answer:

  • Specific software they prefer using 
  • A logical reason behind their preference
  • How the software has made them more efficient

Example:

“My favourite tool has to be Lobito. I've used it several times and every time it delivered outstanding results. I prefer using Lobito because it's user-friendly and has well-developed graphics. It also has a short response time that streamlines the testing and documentation process."

How would you deal with the release of a product with defects?

Errors occur even in QA despite efforts to avoid them by QA engineers. The software can sometimes fail, and the result could be a faulty product released into the market. It would be wise to hire a candidate who can react favourably under such circumstances to achieve the best possible outcome for the company. A suitable answer includes:

  • Excellent communication skills
  • Problem-solving skills
  • Ability to maintain composure

Example:

"I'll first alert my team about the fault so that everyone is aware of the issue, and then come up with ways to improve the issue. Once we have our solutions, I'll then call for a press conference to alert the public on the error and urge them to stop using the product while we implement solutions to the problem."

What is testware in QA?

Testware is an integral part of quality assurance. A good candidate would explain what it is and why it's essential for quality assurance. They can also cite instances when they used it in previous employment as a QA engineer. What to look for in an appropriate answer:

  • The understanding of testware
  • Reasons testware is important in QA
  • Experience using testware

Example:

"Testware describes all the materials required to perform a test. It's used to plan, design, and execute tests in QA. In my last job, I used testware whenever we were implementing the testing process to ensure the test went smoothly and we found any issues before releasing the product."

Why did you go into quality assurance?

Understanding the candidate's motivations for pursuing a career in QA gives you more information on who they are as a person. It also helps you determine whether they'd be a good fit for your company based on their values and work ethic. A suitable response includes:

  • Their reasons for pursuing a career in QA engineering 
  • Personal experiences that inspired their choice
  • Personal values they exercise in their work

Example:

“I've always been fascinated by how and why products are released. I realised that I wanted to be one of the people working to ensure that a product is safe for use. Also, I've always been interested in providing quality products and services, and it only made sense to pursue a career where I could live my passion."

Why should we hire you?

This question allows the candidate to sell themselves and their skills. Also, it informs you on whether they did any research on your company before the interview. A  good candidate would match their skills and experience to your company's needs. A good response includes:

  • A confident expression of why they're the best candidate for the job
  • Knowledge of how your company works
  • how their skills and experience would be instrumental to your company's progress

Example:

"I'm the best person for the job because I possess knowledge and experience that would increase your company's efficiency. I did some research on your organisation and discovered you lost a large portion of your clientele due to faulty software. I can assure you that if you hire me, I can turn your prospects around and help you gain more customers and improve your reputation."
