Capgemini Sr. Consultant interview questions

I had given the interview in Capgemini last month for Pune location. There were 2 technical rounds (L1 and L2), I had cleared both the technical rounds. On the same day I got the call from HR and they asked me for the documents for background check. After that I got the salary break-up sheet from HR and I had accepted the given offer (less than expected). BUT after couple of days when I called HR and asked about the offer letter then they said that the job location has been changed to Mumbai and rejected my application. :( Happened twice with me, after selecting in final round HR had not released the offer letter. :(

Attended a huge walkin drive in March. Process was well managed. There was a written test with 5 sections covering Java J2EE Spring Hibernate and Database concepts. The test was supposed to be completed in 1 Hr. It was pretty simple. Then one technical interview and HR interview happened. I cleared all the rounds, but did not receive offer. I sent all the documents they wanted and even accepted the salary breakup they shared. Till date I am waiting for their offer. Don't have any hopes left. Those attending interviews of this company, BEWARE clearing all rounds does not mean you are selected
