The first step of the interview process is a phone screen. After the phone screen, you receive an email with written questions. The last step would be an in-person interview.
The phone screen had very generic questions. The recruiter was very friendly and easygoing; I love hearing an occasional friendly laugh on the other side of the line. This step was not intimidating at all.
From what I know about other applicants, Stripe is looking for very specific qualities in their User Operations applicants. From the broad questions; it seems very difficult to pin-point what exact qualities they are looking for. If you get the position, you know it'll be the right fit!
Good luck!
