Google Project Manager interview questions

It was a very disappointing experience. A PM asked me to develop the case for a hypothetical flight service, broad scenario with no room for clarifications. He kept interjecting constantly as I was trying to develop the case, seemed anxious and rushed from the start, interview started at 5pm, I felt he was eager to get done and a bit rude. This was my impression only.

3 rounds - technical, leadership, and product sense. Really enjoyed the process. Very well coordinated. Team match was a bit frustrating since the teams that were hiring didn't seem that great and leveling was off too for those not coming from FAANG.
