I was referred by one of my collegues who had scored a position there(not joined yet). 2 technical rounds of about 15-20mins each. The only positive thing was the time period of each interview. One advice to the hiring committee, you're job is not just to interview the candidate but make them comfortable as well. No one knows everything and if they say they don't know something, don't stare at them continuously for god's sake. Try to break the tension and if you think that the employee is not suitable, just tell them. Don't smile at them while staring them. That moment itself i forgot everything, my technical expertise, java and even my address. I was a bad candidate but the interviewers made it much worse
