Application Developer

These sample Application Developer interview questions will help you test technical skills and identify qualified candidates for your roles.

Application Developer qualifications to look for

Application Developers use programming languages and operating systems to design functional programs and applications (a.k.a. ‘apps’).

Junior positions may require a degree in Engineering/Computer Science along with a relevant internship. For a senior-level role, top hires will have solid experience in the Software Development Life Cycle (SDLC.), along with relevant education requirements. 

Use a written assignment to test your candidate’s coding skills. 

Keep an eye out for candidates who:

  • Are passionate about their field
  • Love working on side projects 
  • Keep up current with the latest tools
  • Take initiative to contribute fresh ideas

Top tip: Hire candidates willing to grow by making sure their personal career goals align with your company's mission.
