I have background in enterprise software companies with C/C++, so I was glad to receive a call from a recruiter after I applied online at Stripe. Phone screen was a straightforward coding question. Onsite consisted of a couple of coding questions, debugging, and a design interview, followed by an interview with the hiring manager. For coding interviews, actual code on a machine is required, and no whiteboard solution. Questions were not tough; however, the expectation was that the code is complete and working within 45 mins. I'm most comfortable with C++, but using a statically typed language during a coding interview versus using a dynamically typed language like Python or Ruby turned out to be a huge disadvantage for me. I felt I got most of the questions 90%, but couldn't complete the solution either due to some compilation issue or understanding a new C++ library to be used to solve the problem. Interviewers were pleasant, and overall I felt welcome.
