1st round was telephonic.2nd round was a technical round with brief discussion on the project. 3rd round was again a technical round .Final round was with a senior manager.It was a general discussion about project and expectations.

Backup candidate strategy (They will not give you offer even all rounds gets clear) I gave 1 Technical and 1 Managerial Round. Both the round got clear. But then they dragged next process to next 2-3 months. I asked for reason on chat, mail so they not replied, Then on third follow up they replied saying due to business reason we are not filling this position. But i am sure its Backup candidate strategy by HR Where they will keep dragging process untill earlier selected candidate joins their company.
