a programmer sits in front of his computer. He is in the home office, and we can see sun shining behind the window.The good news is that you won’t compete with many other people for the job (of REST web services developer, or tester). One or two other applicants, and sometimes you can even be the only one.

The bad news is that all people competing with you in an interview will have strong technical skills and proficiency in the programming language.

That means that your great answers to technical questions won’t suffice you to land the job. You will have to convince the interviewers of your soft skills, right attitude to work, and value you can bring to their company.

They will ask you screening and behavioral questions to understand your attitude and motivation. If all shortlisted candidates handle the technical part of the interview, the person who handles better the non-technical questions will get the job.   

In this article, however, we will focus on technical questions. If you would like to see the other questions, navigate to the following articles:
