Web Developer Interview Questions

Web developers are responsible for designing, coding and improving web pages and online applications. You should look for candidates with similar experience and excellent coding skills.

Your ideal candidate should be passionate about software development and have a demonstrable application portfolio. To complement your evaluation, you can give your candidates an assignment, close to their position’s requirements and assess if their performance matches your company’s needs.

For computer science related positions, it’s a good sign to spot a desire to learn and a continuous interest in technology development among your candidates. You can ask how they stay informed about current industry trends and if they attend relevant seminars. Being active in technical forums or engaging in side projects, like game development, indicate an inquisitive candidate for your web developer position.
