QA Interview Questions and Sample Answers

QA Interview Questions and Sample Answers

When looking for an employee, business owners usually go through numerous CVs and interviews before they spot a suitable candidate. However, it still happens that a seemingly skilled employee doesn’t fit your company values and can’t work in the team. That’s when QA engineer interview questions step into the game. There are different types of these questions, depending on the expected outcome, but based on our experience, Qubit Labs has decided to divide them into four major areas, including:

  • hard skills;
  • soft skills;
  • logical;
  • behavioral.

You need someone to analyze quality, prepare and set standards, prevent mistakes, and improve the project. The person has to be able to say when something’s wrong even when others can’t see that. An experienced QA understands the product logic and knows all the nitty-gritty of the project, like requirements and current status.  

A typical working day of a QA engineer includes:

  • testing, creating test cases, and bugs documentation;
  • checking the bug-tracking systems on fixed bugs;
  • meetings;
  • going through the requirements and clarifying them with the clients;
  • communication with the developers;
  • designing test documentation.

The issue is the following: what QA interview questions will help identify a perfect candidate right away and help to understand that he/she fits the company? This article is your cheat sheet on asking the right QA test interview questions and hiring the right people.

 

Questions to Check Hard skills

 

Please explain what a software life cycle is.

Why ask this question?

A QA specialist has to understand that when developing products, there have to be certain deadlines to make it easier to spread the load for the team and let the client know when the work will be finished. By asking such interview questions for QA engineers, you will see the candidate’s readiness to meet the deadlines and the overall understanding of the development cycle. 

Besides, the interviewee can also explain the related concepts, like methodologies, and it will be a huge advantage both for him/her and you as an employer because the candidate has a significant level of knowledge.  

Example: a software life cycle is a time period starting from the moment when the concept of software appears and finishing right when using the software is no longer possible. It includes several stages, like a concept, requirements clarification, design, launch, testing, installation, and maintenance. Also, various methodologies are applied for software development, such as the Waterfall model, V-model, Agile model, and Scrum model.

 

Please describe the verification process and explain it.

Why ask this question?

Similar QA testing interview questions and answers help to see whether the candidate understands the real meaning hidden behind the mentioned wording. One should identify whether the product is being built correctly. The verification process ensures that each stage of the software life cycle follows the predefined requirements and specifications and doesn’t deviate from them.  

Example: the verification process helps to ensure that all the product functions perform smoothly and are logically correct. The verification structure includes several components, like reconciliation of validated requirements, technical documentation, and correct implementation of the program code at any software development and testing stage.  

 

What is functional testing and what types do you know?

Why ask this question?

This is one of the most common QA technical interview questions. Functional testing is one of the types of testing, which is aimed at checking whether the functional requirements of the software correspond with its actual characteristics. Suppose the candidate understands the goal of functional testing. In that case, one will be able to define if the software has the ability to solve the tasks set by users in certain circumstances. 

Example: usually, functional testing includes black box testing and isn’t applied to the initial code of the product. Its goal is to check each function of the software product, ensuring the relevant input and assessing the output per the functional requirements. This activity focuses on four essential elements: core functions, basic usability, accessibility, and error conditions.

 

Also, there are some other additional QA testing interview questions you can consider asking:

  • What is non-functional testing?
  • Explain the bug priority.
  • Explain the code coverage.
  • What is the validation process?
  • What is a test case?
  • Explain the testing matrix.
  • What is risk analysis in resting?
  • Walk us through the process of writing a bug report.
  • Walk us through the testing process.
  • What is performance testing?

In case you are looking for senior-level developers, you might look for other QA interview questions and answers for experienced professionals. Their areas of expertise are more advanced, and they can deal with more complex issues.

And if a person prefers the second option, then you ask whether he/she can collaborate with the colleagues from time to time to ensure they are on the same page.
