Interview Preparation Tips

Round: ONLINE CODING ROUND
Experience: Facebook visited our campus in July, 2012. We had an online coding round hosted on InterviewStreet. We were asked to solve just one problem. The given problem boils down to : Given a undirected graph, source and destination, write the code to find the total number of distinct nodes visited, considering all possible paths.
Tips: Those shortlisted had to fly to Delhi for a Personal Interview. There were four rounds of interview, each of 45 minutes. The questions were simple. But just solving the given problem wasn't enough.

There was much more interaction and short questions asked related to the problem

Round: Technical Interview
Experience: The above mentioned questions wer asked in the interview. For every solution I was asked to write the code on paper. The code should also include the implementation of the data structures used (I used heaps - so I was asked to implement heaps ). They are looking for someone with good problem solving skills and conceptually sound in data structures
