I had a phone interview with the hiring manager, we talked about basic project management role and we discussed what's the difference between program manager and project manager.
I got invited to an on-site with 5 interviewers. I first met with the Group Program Manager, and we started with a design question on electric car, and the problem to solve was how to we can get an electric car charge quickly so we can drive across the country without waiting.
Then I had two interviews with two PM leads, one of them focused on my pitching skill. For this one, I was asked to pitch as if I were talking to Ballmer. It didn't go well since I haven't thought of getting question like this before. Next I was asked to make a quick sales pitch for my product (a 2 mins pitch at, say a product fair). This was much better, and he had follow up questions (pretending to be a real audience).
The other lead asked a scenario question which I was totally expecting it. He described the scenario, and I work on getting the information from him. Get all info before making a suggestion to the problem.
The next interviewer focused on pure design question, I think the question was about designing a vending machine, but I couldn't remember the details. Certainly things to remember is to find out what problem we are trying to solve or what value we are trying to provide with the product/feature we are designing.
The last interviewer was the Director of PM, not so technical. Mostly focus on why a PM role fits me. Also asked me which interview was good, and which was bad, and of course, why. He did a short follow up on one of the question, but I couldn't recall what he asked.
