Written and F2F In F2F interviewer was discussing the question asked in written.I explained how I solved the problem.I also mentioned that the problem is called Dutch National flag problem but interviewer was least interested.He gave another problem and pulled a chair and stretched his legs on it as if sitting in a beach.He asked some more general questions.At the end I asked what does he do? He told he belongs to some other team he is just doing the interview for them.
