I received a call from Recruiter and the interview was arranged. No proper communication about it The interviewer asked some oops questions which I have answered, then started lot of questions on multithreading which I answered as well then kept digging at all the concepts which are never heard of. I don't understand these kind of interviewers fetish where they ask some lame unnecessary concept nobody uses. they should ask how a person is able to think, if he can think he can solve any problem.
