Google Software Engineer, University Graduate interview questions

First step was writing an online test consisting of 2 questions within 60 minutes. However I could attempt only one question. Cleared the online test then had a phone discussion with the HR. She provided me with the study material and explained what Google mainly looks for in a candidate. My technical screen could have gone better. I couldn't understand my interviewer's accent so had to ask him to repeat his questions many times. I had a difficult time understanding his accent and I believe this wasted my time and he could not ask me more questions. It depends a lot on who you interview with!

3 round cleared. Nice interview. Second and third was all technical. You should no the complete core java, algorithms, data structure very perfectly. You should also know the hash tables and linked list well. At least one programming language you should know perfect.
