The hiring process is of 4 rounds.Interviewed for Atos at Vikroli office on 25th June 2014.Though i was selected the HR didn't send me offer letter. The company selection process is not lenient. They gave me silly reasons like they mailed me offer letter and i haven't received and you can not join now as joining date gone. So if you are going for the interview and get selected please ask for offer letter immediately .Don't get fooled like me.
