CGI Software Engineer interview questions

Interview will be started with Face to face two rounds technical then managerial and HR round. Offers will be issued after checking the back groound process. It takes Some time to release the offer.

Was called on a Saturday for the interview. Had two rounds of interview. Both technical. Was told that I cleared both and will have a HR discussion next week. Did not hear from them for a month. After a month a different recruiter called me and asked me if I would be available for a coding round; to which I accepted. A 6 hour long coding interview took place. Passed the round and was offered a first draft of the offer. I negotiated a higher salary to which they accepted. Two weeks passed by since then. I sent a follow up mail to which they responded "Please look for other opportunities." What the hell!
