I applied through a recruiter. I interviewed at Google
Interview
Hiring process starts with phone screen. Once you are through it, you are called to Google head quarters in Mountain View, CA. Here I had 4 rounds of interview and a lunch break in-between. They book tickets for your travel and hotel and reimburse your expenditure during your stay. I must say Google HRs are really helpful in making me understand entire interview process and giving suggestions for the same.
Interview questions [1]
Question 1
None of the questions were unexpected, Be sure you know data structures like Maps, Trees, Array/Lists well and Time complexities. They usually ask time complexity of your program in the end of the solution u gave. Even read about OOD and be thorough. Again, its Google so make sure you prepare our best :)

I applied through an employee referral. The process took 4 weeks. I interviewed at Google (Hyderābād) in Mar 2013
Interview
I applied through employee referral. HR called me within two days after sending resume. A phone interview is arranged a week later. I was interviewed by a SET from Bangalore. He asked me simple coding questions and writing test cases for it. I was informed that I've cleared the phone screen within 2 hours. Then onsite interview is arranged two weeks later and I flew to Hyderabad. I had 5 onsite rounds each consisting of 2-4 questions. Questions were focusing on efficient coding using data structures, writing test cases for it and write test code. During the interview I was continuously updating my thought process to them which helped me to get nice hints from them whenever I deviate from the right path to solution. I was able to ask them many questions relating google products and SET's work and they were answering my questions patiently! I was taken to cafe with another SET for lunch where I got to know the work environment and other related stuffs! The overall interview process was good. I was constantly updated by my HR about the feedback processing and I got my results in two weeks time!
