The worst HR phone interview I ever had. HR yawned during this interview, explained about the company in very boring manner like read a prayer. Without any clear explanation about technology stack. Invitation to the first interview was non professional at all. The interview with VP R&D was better but at least was clear regarding expectations from the candidate. This position is very product features oriented without technical improvement or progress for a candidate/employee. Good for people who will like their domain. The interviewer created the impression of a very difficult person whose opinion is the main one and the other opinion is not accepted in attention. Apparently, the technical solutions in the company were accidental without proper verification.
