Application Developer Interview Questions
Application Developers work with one or more programming languages and operating systems to design functional programs. Their role is to understand user requirements and build features that meet these needs.
Depending on the seniority level of the position, you may want to look for candidates with several or few years of work experience. For example, for junior positions, a degree in Engineering/Computer Science along with a relevant internship may be enough to qualify for the role. For a senior-level role, look for candidates with solid experience in the Software Development Life Cycle (SDLC.)
As with all technical roles, it’s best to use a written assignment to test candidates’ coding skills. Also, keep an eye out for potential hires who are passionate about their field and take on side projects. They’re more likely to contribute fresh ideas, inform their team about new tools and perform well at work.
