My interview with Google spanned a couple months. The first was for a Program Manager I didn't actually apply for (but was similar to one that I applied for). After an initial phone screen with the Recruiter, I was set up for a Google Hangout interview with the hiring manager and then they flew me out to Mountain View for a series of interviews with various people from the team, and a person from outside of the team. I ended up hearing back from them a couple weeks later that while the team had a lot of positive things to say about me, they didn't think it would be a good fit for the role. The Recruiter actually passed me onto another Recruiter, because they thought I would be a good fit for another role within the larger organization. It's great that they take the time to really think about where you would fit into the organization if they think you bring valuable skills and experiences to the table. My second set of interviews went rather fast. I went through the same process of having a phone screen with the Recruiter, having a Google Hangout interview with the hiring manager, and then being flown out to Mountain View again. This time though, the Recruiter didn't get back to me with feedback until I emailed her twice. This kind of shows that the Google interview process is really hit or miss; sometimes you would end up with a great recruiter and other times, you'll get one that's pretty useless.
