I applied through an employee referral. The process took 4 weeks. I interviewed at Google (London, England) in May 2012
Interview
I was contacted for a phone interview. The questions tested basic competencies in algorithms and data structures. I was then invited to a series of 5 onsite interviews. 4 out of the 5 went well, but the fourth was with what Steve Yegge would describe as my "interview anti-loop". He presented the problem, told me to solve it and then sat down and stared at me..
Interview questions [1]
Question 1
The Skyline problem (Google this). It is not so difficult, but under the circumstances I was unable to come up with a solution.
