They have taken 5 technical rounds of interview at the end of the interview they will ask which is your native place if you are from Tamilnadu they will hire you or else they will simply reject you even if you have done well in all the technical rounds.

2 technical round and 1 client round. Very bad experience they took all the round and then said we wont move forward as we are having low budget. Last round they told face to face with client but never happened. Very slow process. I think interview process could be better check candidate budget at start so that unnecessary time wont waste.
