CGI Senior Systems Administrator interview questions

Interview was scheduled at 10:00 in the morning but they took the first round at 3pm in the afternoon. There were three rounds and 2 were technical and the third one was HR. I have cleared the first two rounds and the HR said you will be getting mail asking for the documents then we will release the offer. They sent a mail after 10 days and even after a month after sending the required docs there is no response and there is no reply to the follow up mails. There were few more people who attended the interview with me. It is the same with them.
