J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Jane Street (New York, NY) en mai 2012
Entretien
Applied online, got emailed to schedule interview within 3 days. Email communications very effective.
On interview day (1st round), person called right on time and the interview lasted for around 30-40 mins.
2nd round, the person called 20 mins late and the interview lasted for around an hour.
All of the interviewers are traders and they seem to like their job and the company. Very friendly and helpful. They offered help with I got stuck with the problem.
Advice: just calm down and think about the problems analytically.
Many rounds of brainteasers, some of which are more rapid fire in nature and others which require you to flesh out a detailed answer to a complex problem. Be well rested and well prepared!

mostly maths probability questions - a lot of conditional probability, relatively easy in the first round, but you need to think out loud - you need to be really fast

4 rounds in final. The first one is market making of cards. The rest are especially designed games. The interviewer may ask added question along the playing of the game
