Our interview process is designed in such a way that we check the basic knowledge of coding. Candidates who have basic knowledge of coding solve 3 to 4 questions out of 5 or 6 questions and get selected for further round. We have been able to recruit very good developers through the process where they just don't copy codes from any website but they themselves write logic on the paper. Please note that we don't ask for the whole program on the paper but just the codes.
