It was on 03-14.Within 2 days they scheduled for onsite interview.By the way what all design pattern questions they asked you in first round?I was asked only Observer Pattern and Singleton Pattern

Ya the same thing.....I already listed right...I had a difficulty in answering Observer pattern so listed here so that others can prepare well :)
On site they will ask to write small code I guess but not so complicated. I heard that fidelity interview is not that tough as tech companies. So prepare well, answer confidently. All the best for the interview.

Dude my onsite is scheduled next week. So I dint have any experience to share apart from the phone interview questions. Now its your turn to share the experience so that I can do somewhat better next week. So please do share your experience.

I had my phone interview this week.The interview didn't go well but I have a similar interview with the same company in a different location.Can someone please tell the questions that were asked onsite?

I heard that the questions asked on onsite were related to map reduce scenarios like how to approach a situation (which the interviewer tells) and develop map and reduce tasks (orally not written). Different behavioural questions apart from these.
