100+ testing interview questions for beginners to get hired

Let’s face it.

Having a successful interview is a crucial step to becoming a software tester. It’s a “make it or break it”.

But passing an interview is hard. We all know this. It’s even 10x harder if you are a beginner in software testing when you do not have much knowledge and experience in both testing and interviewing. However, there’s no way that beginner cannot have a successful interview.

The secret? Be prepared!

Success is where preparation and opportunity meet – Bobby Unser

In this post today, I would like to introduce you 100+ software testing questions which are very very likely to be asked in the interview for tester position. By knowing these questions and getting prepared before going into the interview, you will be more confident and have a better chance to pass the interview.
Some important notes:

  • I know… I know, some of these questions seem to be too general (and boring) to make sense to you, but how can I say…they are still asked in the interview. Anyway, our goal is not to prove that. Our goal is to pass the interview.
  • Some of you may ask for answers for these questions, but I don’t have the time for now to provide reference answers for these questions. Don’t worry, I’ll surely do that soon. So, if you are interested in the answers, just let me know by entering your email address below.

Final thought

There you have it, 100+ software testing interview questions to prepare for your interview. Like I said before, this list is not an exhaustive list, so don’t just solely rely on these questions to pass the interview. The reason is because the interview may change the way they ask the questions. What you should do is get to know these questions and see if you can answer them using your own words and knowledge. If you can’t, go and find out the answers by yourself.

So, that’s it!

I wish you luck and don’t forget to let me know how your interview is going 😀
