Google Engineer interview questions

My on-site interview had 5 rounds. The questions were quite simple. I went in expecting to be grilled on a lot of theoretical computer science, but the questions were of a very practical nature. All the interviewers were extremely nice and helpful with giving hints when I got stuck. Overall, a very positive experience even though I didn't get hired.

one telephone, 1 day on-site, 5 engineers, each 45 mins. various problems from the interviewers themselves. Each problem needs to be solved by coding rather than describing the overview. Not specific algorithm to be answered, all are integrated in a virtual problem.
