Stripe Software Developer interview questions

One Skype interview (a not-too-difficult algorithms question), then the in-person interview, which consisted of a simple algorithms question, a find-the-bug question, a systems architecture question, a design-and-implementation question, and then a chat about company culture and the interview process with one of the founders. Everyone was very pleasant to be around, and the food was quite good.

I applied for a development job advertised as requiring broad development skills. My resume shows me as being an experienced engineer and also shows my educational background quite well. I was asked into a phone interview with screen sharing where I was supposed to implement a certain, artificial functionality. The interviewer expected one specific approach to be used, and the whole interview was then revolving about me not having his idea. He then went on to ask a few basic CS questions about my approach, but apparently he lost interest in me early in the process.
