Had applied online was shortlisted for the phone interview. There were 3 phone interviews:

1 st round : It is done to check if you fit the bill. It was simple Q and A with most questions being about the education and some personal questions. I cleared this round.

2nd round : It's a managerial phone round. There were no technical questions just a normal talk about your interest and was briefed about what the company was into.

3rd round: This was a technical round. Was grilled for close to 1 hr. Everything which is on your resume should be known. Was asked 9 questions and I answered 7 of those. Didn't think would clear the round as I thought it wasn't convincing enough but was told I have cleared the round and was invited to their office for face to face round.

Had a total of 8 rounds in the office for 2 days:

1st round : Was with India head HR. Went well and he seemed to be impressed

2nd round : This was a case study round wherein I was asked 4 questions on some image processing problem. Hadn't done image processing anytime before but was briefed about it and told that it was enough knowledge to solve the given problems. I could only solve 2 questions and my other two answers were pretty close. Though not convinced they let me into the next round

3rd round : Its was a technical presentation. I was grilled by a panel of close to 8 people for 2.5 hrs.

4th round: They asked me to re-do the 2 problems on image processing case study which I couldn't complete previously. I cleared this round as I was given a few hints.

5th and 6th : It was a telephonic conference with people in USA. It was a behavioral and leadership round. I cleared both the rounds.

7th round : Was given a problem and asked to solve which had an open solution. The question asked was "Estimate the number of petrol banks in Bangalore city".

I was taken aback by the question and gave some dumb answers but after getting some clues I gave them a solution which they said was the right one. As they were not completely convinced, decided to hold another round.

8th round: Again an open ended question : "Estimate the number of baby diapers used in India /day".

Though I gave them a decent solution but I was shabby. The intense pressure I was put under for 2 days had its toll on me as I cracked and wasn't confident enough. So was told I hadn't made it!

Estimate the number of baby diaper sued in India everday
