I applied through a recruiter. The process took 4 weeks. I interviewed at Google (Mountain View, CA) in Apr 2015
Interview
The process was quite involved. It started a 3 rounds of phone interviews and then I was finally invited to come up to Google HQ for an onsite interview. I arrived on site and met with the HR coordinator first and then a series of other Google PMs who spent about an hour each with me. There were no algorithm questions but al lot of open-ended product design questions
Interview questions [1]
Question 1
A number of "product design" questions such as "How would you design ....". The goal was to access my thought process and problem solving skills
I applied through a recruiter. The process took 3 months. I interviewed at Google (Mountain View, CA) in Jan 2016
Interview
They are clear about the steps and length involved. The questions are hard and abstract. However, some of them get a bit too far fetched and makes me wonder if they aren't more in the brain teaser territory. It was only Product Managers interviewing with "case" type questions the entire time.
I applied online. The process took 4 days. I interviewed at Google (Bengaluru) in Feb 2012
Interview
It was good but hard. They asked me a lot of questions and used words like Googly. I liked most of the interviewers but some rather ideological in their perspective. I'd recommend the experience to a friend.
