They have 3 technical rounds of interview but even though you clear all the technical rounds they will not give a proper reply atleast for 3 - 6 months, personally I faced this situation. I gave interview for capegemini and other companies got 2 offers after joining a service based company and completed my 2 months, then these capegemini HR people called me for Salary discussion and offer letter. Thank God I didn't join Capegemini
