Don't waste your time with them -- I had huge expectation from this company as they are in Forbes top list, anyway. I was interviewed almost 9 times.

1. HR call
2. Online test
3. Telephonic technical interview (C#, SQL)
4. Again telephonic technical interview (Data structures and time/space complexity)
5. Face to face interviews after 2 weeks. - First online assignment of an hour in their office
6. Hiring manager spoke with me, again technical interview
7. 2 people from their technology team
8. Again 2 different people from their technology team (same person from my 4th round)
9. General discussion with HR

All interviews were of at least 45-60 minutes. I have interviewed at least 1500 candidates in my life. Is it really required to take 9 rounds of interviews to check someone?? And to find out there is no best suitable position for the candidate in the company? (Finally they told me there is no best match for me in their organization.)

Seems like they are training their people to conduct real interviews. It was 1.5 months of process with huge disappointment at the end.

Don't wait for their offer if you have something in hand already.

Questions on data structures, algos, C#, WPF/WCF, databases (joins etc), design patterns, derivatives.
