Google Software Development Engineer interview questions

I applied online, and got a chance to be interviewed at the local office. There were two rounds, each with two questions. First round, got the questions quite smoothly solved but did not finish the code in 45min. Second round, the interviewer got problem with the hash function I was proposing and did not lead to the coding stage.

This a phone interview. Firstly, I was told to briefly talking about my working experience before my master degree and my course project, then he ask some fundamental questions about binary search tree and hash table, and compare their usage in different conditions. Then he ask two coding problems.
