In March 2013 I applied for a Product Manager role in Europe. I had a preliminary screening call with one of their recruiters, which was really useful. In fact, I found the recruiters to be really helpful throughout - sending through cheat sheets for the interview, etc. I then had a call with a London-based Product Manager who had been in the role for 4.5 years. It was supposed to be a 45 min call but he rang late, so the whole thing felt really rushed. He didn't really refer to my CV at all, but seemed to be following a script. All throughout it felt like a game of fish - I obviously wasn't giving him the answers he was after. It was a frustrating experience. I got rang the next week and told that I didn't have the product management experience needed at Google's scale. That was a frustrating answer, I thought they were interested in me precisely because I didn't fit the standard profile (I was the CEO of a UX firm).

You would have to do a hiring assessment first, then a recruiter screening follows. First round interview with the hiring manager. Majorly product sense and product improvement. The questions were not direct though.
