What to expect in your Web Services Interview?

Last updated on July 18th, 2018 at 06:29 am

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 will try the luck with you, and sometimes you canbe the only person who tries to get the job with the company.

The bad news is that all people competing with you in an interview will have strong technical skills, and proficiency in the programming language. It will be a close battle. Let’s learn how you can win this battle.


More than tech skills

You should realize that knowing the right answers to technical questions don’t guarantee that you will end up with a new job contract. Since most job applicants will also know the answers to technical questions (or at least to most of them), some other things can make a difference at the end of the interviews.

So, who will get the job at the end?

Typically the person who manages to convince the recruiting managers not only of their technical skills, but also of their soft skills, right attitude to work, and general readiness for the job. 


Questions that target your attitude

Interviewers will ask you some screening and some behavioral questions. Your answers to these questions help them to understand how you’d approach various situations in the workplace.

They will see whether it is a pleasure to have you in an office, whether it is easy to talk to you, and whether you won’t have problems each day, while trying to co-exist with your colleagues. These things are very important for each employer.

Conclusion: If all shortlisted candidates handle the technical part of the interview, the person who handles better the non-technical questions will get the job. Let’s have a look at some of these questions.

  • Why did you apply for this job?
  • What motivates you to work hard every day?
  • Why did you leave your last job / Why do you plan to leave your present job?
  • Describe a time when you struggled to meet a tight deadline.
  • Describe a time when you experienced conflict of your personal and professional interests.
