Google Software Development Engineer I interview questions

The interview process is pretty straightforward. There were two back-to-back interviews. I was a bit surprised by the first one's fast pace and mess it up. The second one was much better but it didn't help. I was rejected by call and email. The first one is mostly some small questions like the derived classes, binary search and dfs. The second one is much more complicated. Obviously I could finish it in 45 min, so the interviewer directly ask me to write only key functions. At last we were still in short of time, so the pseudo code was also allowed. I'm pretty sure I did well in the second part.
