I got a nice interviewer who was very polite and patient. Sometimes I could not hear very well as he seemed to be on some busy trading floor. Got asked a lot of mental math questions which I found quite hard, e.g. 3 digit numbers to be multiplied. I then got asked what I thought was the probability that I had all my answers right. Then they asked some probability brainteaser questions.
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.

Two players, flipping a coin until one player wins. A wins if the roll ends with HHT. B wins if the roll ends with HTT. What are the odds B wins the game.
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
