The interview process consists a hackerearth online test followed by two tech + HM discussion round. The online round is medium level coding questions and some MCQs.
The next round is a technical discussion round. In this round, the interviwer who himself has recently joined was keen to knowing exact method names of any coding question he may ask.
It seemed he wanted to listen only what he has done or known. If you solve the question by any other way than what he himself is aware of, he will try to argue and will keep asking "is there any other way". He hopes that either candidate answers what interviewer has known or he is rejected.
From his questionnaire, he seemd like a person who validates his "knowledge" in interviews from unsuspecting candidates.
