Multiple phone interviews, followed by invite to campus. I was given 24 hours to complete a case-study prior to the on-campus visit. I had several interviews across departments and presented the case-study results to my interviewers together.
I applied through an employee referral. The process took 2 months. I interviewed at Google (Mountain View, CA) in May 2015
Interview
Very quick and transparent process. You have a phone screening with the recruiter, then you submit your case study, then phone interview with team member. Finally onsite interview. They ask you very analytical questions, nothing too behavioral. Ask about experiences that apply to a strategic way of thinking and how you have used skills to make improvements in the past.
I applied online. The process took 7 weeks. I interviewed at Google (Mountain View, CA) in Oct 2015
Interview
Applied On LinkedIn. Received a Phone Screen from a recruiter to gauge interest in the position and then another Phone Screen from a recruiter a week later with similar questions. The recruiter then sent a case study related to the job position that was to be completed in 24 hours. I moved on to the next round which was a 30 minute Google Hangout session with one of the hiring managers who described the job position more in depth and asked mostly behavioral questions. A week later they flew me out to Mountain View for the final round, which consisted of a 30 minute presentation to 3 hiring managers and three other 45 minute interviews (tougher questions) with different hiring managers on the People Operations team. Was supposed to have one more interview after lunch, but "something came up" which I assume means they made their decision already that I will not be moving on. Nevertheless, it was a great interviewing experience and the recruiter did a great job of being helpful and responsive throughout the whole process.
