Google Software Development Engineer interview questions

I got a mail from one of the recruiters first. Then there were two phone calls. First one was a basic phone interview where she explained the interview process. Next was a technical phone interview. I was asked to code on a shared doc. Generally they ask two questions. But I took a lot of time for the one itself. Hence was not selected. Questions are not that tough. Require coding knowledge.

Phone Interview with two questions. One sorting problem and one DP problem. Got the solutions right but might not in the most efficient way. Spent too much time on sorting problem.
