Ho presentato la mia candidatura online. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Jane Street (Hong Kong) nel mese di ott 2014
Colloquio
Submitted my application through their website, and was invited to schedule a phone interview a week later. Questions involved mental maths and probabilities.
Probability of getting two queens in a deck of cards. Flip four coins, the probability of getting two heads. You and I play a game, we roll two dice and both pick a number before rolling them. The one closer to the sum wins. What is your strategy? Go first or second? Now imagine that we have a non-uniform distribution, with 40 % chance of getting a sum of 12 and a uniform distribution for all the other numbers. What is your strategy? Go first or second? Also had to estimate the confidence interval of my answers
Very friendly interviewer and a good experience. At the end of the interview had the opportunity to ask questions about the firm and work culture.

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
