Interview invitation was sent in mail along with the exact date and time. Interview was scheduled on a weekend at 1300hrs. I arrived at the office on time. I was asked to wait in a meeting room till I was called. There were around 40 people waiting, when I spoke to some of them I came to know that they were waiting from the last two hours. At around 1345hrs we were offered sandwiches. At 15:45 I was called for the interview, at last. Interview lasted around 20 minutes.
