The interview process was incredibly fast! First, I spoke with HR, who explained that the process consisted of three interviews – and it was exactly as they said. The second interview was with the hiring manager, and then with the group product manager.
It was super quick: on the same day as the first interview (a Thursday), I was already told I'd move to the second round. I had the second interview on Monday, was told on Tuesday I'd proceed to the third and final one, which I had on Wednesday. That very same afternoon, I received the email saying the position was mine!
