QA Engineer Interview Questions

Quality Assurance (QA) Engineers monitor all stages of software development to identify system malfunctions and help improve product quality. They are responsible for conducting tests before product releases to ensure software runs smoothly and meets design quality standards.

Your ideal candidates should have a solid technical background, as they’re involved in the entire software development process. Use these questions to discover candidates whose past experience matches your company’s specific needs. It’s also essential to look for candidates with strong communication skills, since QA Engineers usually collaborate with various departments (e.g. web developers, designers and product managers.)

For better results, you should check if your candidates practical skills match their theoretical knowledge. You can include specific assignments in your interview process to assess how your candidates handle software problems and if they can come up with effective solutions in a timely manner.
