I applied through college or university. The process took 3 weeks. I interviewed at Google in Oct 2015
Interview
Recruiting process was very nice. Had two back to back 30 min phone interviews, followed by one host matching interview. Recruiter was really on top of things in terms of getting everything scheduled in a timely manner. However, the phone calls were a bit staticky, so it was hard to hear my interviewers.
Interview questions [1]
Question 1
Signed NDA so can't go into too much detail. Basic algorithm questions with run time analysis. Know your data structures well.
The interview process included a couple of on-site whiteboard coding interviews. There were two back-to-back interviews, both with Google software engineers, and the recruiter was around to show me where to go.
I applied through a recruiter. The process took 1 week. I interviewed at Google in Apr 2013
Interview
A recruiter contacted me and set up two back-to-back technical phone interviews. The process was very smooth. The recruiters were very helpful and professional. The actual interview also went smooth, with the interviewers being very nice and friendly. Each round started off with a "what do you work on" question, and one technical programming question. The programming question was not anything hard, but one has to be able to code very smoothly on Google Doc I guess!
