Stripe has some very nice people, which for I wasn't able to find in many other places. My phone interviewer was a senior engineer. They were extremely friendly and kind even though I had some technical difficulties setting up Hangout at first, and later had some issues with my runtime stuff on my laptop.
They brought me onsite a few weeks later. There were 4 interviews + lunch. I liked that for coding questions, you get to work on your own IDE and can google things like apis for libraries. The first interview felt a lot like a normal engineering task rather than a typical problem solving question, which was neat, because I felt like it was closer to reality. The second one was debugging an open source code base. I didn't do well in that one because I wasn't that familiar with the particular subject matter. Also, I felt like the interviewer wasn't as helpful as they could have been but I could be biased. The third interview was the weirdest. It was actually the easiest of all interviews - a straightforward problem solving coding question. The interviewer seemed very detached from the beginning and barely said anything during the whole interview. Unfortunately, I misunderstood the problem statement, and even though I communicated my interpretation of it upfront and asked for confirmation to proceed, the interviewer said sure and didn't catch it until half way into the interview. I had to re-write most of the code because of that. I did finish the coding part and some testing in the time left, but the interviewer didn't seem impressed or happy, just total detachment and a fake and forced politeness. The fourth one was a design question. The question was interesting and the person was nice and it went well.
I got a rejection a day later, and the recruiter (who was very nice) was able to give me some feedback after I asked for it, which was nice. In general the feedback aligned with my suspicion.
Overall nice people and positive experience, except for the one interviewer who didn't really do their job.
