Hiring manager Phone screen followed by a director phone screen then a Face to face interview and lastly HR round. HR round was most interesting and was a very good experience. At present may be HR round is not all that interesting. Now the process might have changed and first round could be technical. There may be more technical rounds based on the necessity.

It was simple based upon my past experiences with other companies. You just need to be confident and be precise with all the questions they ask. Don't need to give them a comprehension based answer.
