Jane Street Intern - Software Engineer interview questions

Applied through their site. The HR are nice people. First interview with a junior engineer. They jumped right into the technical exercise and weren't going to introduce themselves until I asked. They were patient, helpful and answered all my questions thoroughly. Second interview was with an engineer who apparently does lots of interviews. They spoke in some strange accent and it was very hard to get what they said. They didn't know much about OOP and kept interrupting and asking with each line I wrote. Also, they gave brief answers to my questions.

First round interview, standard software question involving coding a calculator program, but be ready for intense criticism of every character your write. Also some unix command questions.
