Ho presentato la mia candidatura tramite segnalazione di un dipendente. La procedura ha richiesto 7 settimane. Ho sostenuto un colloquio presso Jane Street (New York, NY) nel mese di ott 2016
Colloquio
2 phone rounds + onsite (5 interviews of about 1 hour each); fit was only measured implicitly, most of the time was spent doing math questions. Two of the five onsite interviews were collaborative with the other person applying for the internship that day. Problems generally speaking had some sort of tricky edge/corner case to take into account; interviewers look for your ability to identify such cases and to be critical of your own first intuitions. Although there was no explicit fit portion of my interview, personality seems to be evaluated at least implicitly. Also key is keeping cool / staying calm yet not overconfident.

Domanda 1
First round: standard brainteasers; after that, problems were more "real world" and lacked precise answers. Instead you have to be really good at estimating and coming up with reasonable explanations / justifications for your intuition.
I had a phone screening call from a recruiter, they asked some standard probability questions, bayes rule, and expected value about dices. Overall experience was pretty good. Make sure you prepare your probability

Expected value, if throwing a dice, 2 dices and 3 dices with option to reroll.

Colloquio
Very smooth. Around 30mins first round 1hr for the second round. First round consisted of easier probability based questions. Second round was similar but harder and longer questions. The interview process if approached in a calm composed manner should be easier to analyse
multiple phone interviews and a full-day Zoom interview. Interviews got longer and longer over time, but every person was very kind and helpful with hints when I got stuck. The questions get harder as the rounds progress and generally don't have a closed form answer in the later rounds
