1 Round Technical Telephonic, 2 round in office (technical + director), 3 round in office (technical) , 4 Round Hr telephonic discussion. Interview was very easy. Negotiation is really bad. First they will agree to pay what you are asking once you get selected they will come up with very low compared to what you asked. Total waste of efforts you will make. There salary break up is interesting. I bet no one has such stupid salary break up structure. Just a waste of time for a serious candidate.
