Selenium WebDriver Interview Questions


You have been learning test automation with Selenium WebDriver for some time.

You are wondering if you are ready for interviewing for a test automation job.

How can you know if you are ready or you need to learn more?

You can take practical tests (see this link for an example) to assess the level of your knowledge and skills.

You can also go through possible interview questions to find what you dont know yet.

Personally, I dont think that interview questions are useful for taking the interview at all.

But they can help you find what you dont know and should know.

The following list is not complete and it can be improved.

It focuses on testing your practical Selenium WebDriver skills and less on theoretical knowledge.

For some of the questions, I have added links to articles that provide explanations and useful information.

If you have ideas of other Selenium WebDriver interview questions, please leave them in the comments.
