Crafting appropriate software testing interview questions

Software testing is the process of checking the quality and completion of a developed computer software before it reaches the end user. It helps detect errors, gaps, and missing requirements and is executed either manually or with test automation tools, such as Selenium and TestingWhiz.

A good software tester has a strong understanding of software testing technical features. They can analyze complex data with attention to detail and have hands-on experience with automation, defect tracking and test management tools.

As for the non-technical skills, a software tester should be able to deliver their projects on time and communicate testing results efficiently to managers and customers. You can assess the candidate’s technical and soft skills by following these two steps:

  • Ask candidates to complete an exercise that shows their software testing competency and familiarity with testing tools.
  • Ask role-specific and operational questions during the interview to assess how qualified they are for the role. Manual testing interview questions bring additional value to the evaluation process.
