If you're giving someone 6h worth of tasks, you really need to: a) be 100% absolutely certain that you definitely need this to evaluate the candidate (you most likely don't) b) if you do then you owe it to them to study their submission, run it, test it and provide clear feedback and honestly if they've broadly met the requirements you should interview them. The submission could form part of the interview process - maybe you pair program some changes together, or discuss part of the implementation. Basically if someone delivers six hours of work, you use it. c) No matter what, you communicate with the candidate throughout this process. There is absolutely no excuse for ghosting candidates. None
