Round One 30 minute Phone Interview. Interviewer mentioned Jane Street interviews focus on problem solving and dove straight into them. She asked 3 questions, and leading questions that helped me out throughout. She asked me to clarify my answers each time. I was allowed to use paper and pen, but no calculator or computer. I had about 5 minutes to ask her questions about the compamy.
