Stripe has a many staged interview process. There's a phone screen with HR, a 3 hour mini onsite ( at least if you're in seattle ), and then a 6 hour onsite at HQ ( SFO ). Presumably there may be more interviews behind that onsite if you make it beyond that stage ( which I did not ). The interviews are pretty interesting and challenging. The Mini-Onsite was mostly social interviewing like Tell Me About A Time When... , Tell Me About A Challenge..., etc. Stripe did endeavor to prepare me ahead of time for the onsites by providing information via email, and a prep phone call. I suspect that I must have appeared as an interrupt to the person that I spoke to for the prep phone call, as I got the impression that their primary objective was to get off the phone as quickly as possible. The Onsite interview at HQ was much more formally structured than the mini-onsite. There was a presentation section, a design section, and a few role plays. Be Prepared to get very few minutes for your own questions to be answered. Nearly all of the interviews ran right up to the time allotted for them. The thing that was negative about the interview process for me was communication outside of the in-person interviews. Stripe never got back to me on the days that they said that they would ( for the mini-onsite nor the onsite ). I do not know if this is common or not, but I found it disappointing and a source of significant stress.
