Total 3 rounds, Round 1 : Manager round, 2 managers took my interview and it was not much difficult, more of situation based questions. Round 2: Director round, it was very difficult and went for more than 1 hour, lots of technical and situation based questions. Round 3: HR round, was just a formality and background verification was done. Within a week got offer letter, HR person was very cooperative and helpful and most importantly response was there for all my questions throughout my interview process which was around 1 month on an average.
