The attitude of the arrogant interviewer is the biggest concern. The first and foremost guidline which I was thought in my organization during the interview is to respect the candidate and make him comfortable and set the context to accelerate the discussion. But here it's completely opposite. He starts asking as if you are called for a crime interrogation. In spite of our continuous efforts to keep composure and trying to justify he will pinching you to loose your temperament. Probably he might be thinking he was interviewing for a customer voice support executive where your temperament is the key to success. Then his tone will sound like a god of this software industry and he was wrongly placed in this organisation otherwise he should have been in position of MS's SN 😝. But, i must say this is also one learning and couple of good questions that would help me to prepare for my next interviews.
