1st round - written test included question like WAP to implement custom hashmap, Singleton class, Create a Deadlock condition etc., 2nd round - technical round 3rd round - techno managerial 4th round - technical round with client, includesquestions on jvm, memory management and garbage collection etc.I 5th round - techno managerial discussion with client. I cleared all the rounds, rejection was only on the basis of ctc expectation which was as per market standards 30% hike. When NTT data knows they cannot offer the expected CTC then you should not waste candidate’s time, be clear and open in the very start, everyone’s time is important.
