Jane Street Software Engineer interview questions

Placed in stand-by interview. Waited a month, and got a phone call for an hour. Nothing better to add to the pants of the process, but you had to code quickly and fast. Be able to be good at what you're good at, and be confident. Know Python, Java, how to recurse, how to talk to yourself and the most important thing is to be able to write safe and sound code. It doesn't matter if you finish quickly if it's buggy, because it's going to catch his attention and f you up even more later on when he actually picks it out and asks you to fix it.
