The process took 1+ week. I interviewed at Google (Mountain View, CA) in Jan 2011
Interview
This was a pretty strange experience. I was contacted by a Google recruiter on LinkedIn and asked to apply. Of course I did (who says no to Google?) Had a short discussion with that recruiter who said she would pass my resume on to the Compensation team. The Compensation recruiter set up a phone screen with me, but then forgot to call me so I had to call her about 15 minutes late when I realized she must have really forgotten (rather than just running late). She hadn't read my resume yet, so we spent about 30 minutes reviewing my resume (she basically read it to me over the phone), and then she asked me about my Excel skills (which are pretty good because my current job is working in Excel 12 hours a day). That was it. A week later they called to say no offer.
Interview questions [1]
Question 1
If we have 22,000 employees, we plan to grow by 35%, and are going to lose about 10% due to termination during the year, how many employees do we have to hire this year?
I applied online. The process took 5 days. I interviewed at Google (Mountain View, CA) in Mar 2010
Interview
Applied online and received an email that day about a 30 minute phone interview. The interviewer was helpful and informative about the job requirements and knowledgeable about the position. The interview included questions such as 'Why do you want to work at Google' and 'What quantitative analysis experience do you have'. I was told that the whole process if accepted would take about 8 weeks: 2 more phone interviews with members of the team, an Excel case, and then a whole day in-person interview, after which the team would review my compensation package and verify they could create a job description for me.
Got the 'thanks for applying' a week later.
