Google Product Manager interview questions

Google interviews were pretty much as described by others on glassdoor. After emailing with a recruiter, I had a phone screen with an existing employee. He asked about my current work and a Google product I like. A few weeks later I had an onsite with five employees. Each tested a different area: 1 tech, 1 industry knowledge (I'm in cloud computing), 2 market sizing questions, 2 design questions. 2 of 5 interviews were video conferenced. I was surprised by how different Amazon and Google approach interviewing. Amazon digs deep into your past behavior. They ask questions like "Tell me about a time you were in X situation? How did you interact? How did you know things were going well? Not well? What happened when you did Y?" Amazon has research showing that behavioral interviews result in data fairly predictive of future performance. Google doesn't appear to be interested in past experience. They ask questions like "How many X's are in the United States? Design a smart Y (unrelated to you industry). What's the market opportunity of [obscure google product]". Basically think-on-the-spot questions, best answered using whiteboards, napkin math, frameworks and metrics. Both companies have their preferred way of assessing candidates. Both approaches have strengths and weaknesses. After the onsite, the recruiter contacted me a week later with their decision. I appreciated that he phoned me to let me know. Overall, it was an okay experience. Good luck, GCP.
