Once you are sure about the skill set specifications you need to set your prerequisite qualifications.

Check the academic skill set first

One of the prime qualities of a developer is command over the programming language he has learned so far. For example, if you are about to hire a C++ program developer, you need to understand and estimate the skillset level and command over the language he has learned as his professional qualification.

  • Testing real world skill of developers: a coding test can be arranged and shortlisted interviewees will have to take part in it.
  • Finding their team mentality because a project is a teamwork and it has to be done within a stipulated deadline: ask the candidates to play a short game and watch their way f interaction with the team members.
  • The repercussion of getting surprised! Ask the candidates to handle an unusual technical glitch, which is not related to their job directly. Do not expect any outcome in general but check the reaction of the people. The right person will try to solve the problem before raising his voice.
