When the interview started instead of asking me questions and making me comfortable, he began to show off his knowledge and started prejudicing. Though, my interview ran through a duration of more than an hour where I answered more than 70% were correct, but in between he began to loose his temper where I tried to clear my doubts around the questions where it made the interview a lot harder unnecessarily and also I cannot answer some questions which were I already knew the answer of. Such unprofessional behavior was a shock to me coming from a kind of company Deloitte is.
