I went to a career fair and received an interview call. The initial phone round consisted mostly of behavioral questions, with a few others such as how I would test a vending machine and one puzzle. I passed this round and was invited for an onsite interview.

In the onsite interviews, I had six rounds. All rounds involved either programming or testing, or both.

R1) Finding the day when buying an option would yield the maximum stock return, given option values for all days. This was followed by some fundamental theory questions. R2) Creating the nth Fibonacci number in as many ways as possible, followed by questions about trade-offs in various approaches. R3) Building a battleship game. R4) Testing the battleship game written in the previous round. R5) Designing Facebook with an emphasis on the "People You May Know" section and optimizing that search. R6) Testing theory questions and general behavioral questions.

Resume-related questions were asked at the beginning of all rounds.

The whole experience was great and was made even more awesome when I ultimately got the job.

Good luck to all!

All problems had some tricks, but be calm, as they are looking for a problem-solving approach.
