I applied online. The process took 1 day. I interviewed at Jane Street in Apr 2011
Interview
It was the initial telephone interview. I had a few mental arithmetic questions and some probability questions. The person interviewing was pretty nice. He asked about the confidence interval for my answer to the question.

Question 1
I was asked to bid on a car which has a price uniformly distributed from 0 to 100. If I bid higher than the actual price, I can sell it with a price 1.5 times higher. Whats the bid that maxmizes the profit?
Heard Jane Street has exciting internships for female students so I decided to apply. Filled out online application. Received a response for online assessment. The assessment was quite difficult for me. The interview was even harder. Lots of technical questions.

very hard and demanding. they are very selective. they like puzzles and pushing you to think out loud. interviewers are nice though. would possible try in the future. maybe. will see
Asked to play a game and probability - the probability questions were easy, and the game had very little math. It was over an hour, closer to 1 hour 30 minutes. Over zoom
