J'ai postulé en ligne. Le processus a pris 1 jour. J'ai passé un entretien chez Jane Street en déc. 2019
Entretien
Was generally okay, went in too nervous and unsure of my answers and so ended up not getting the role. Stopped at the first phone screen. Guy was pretty nice, but wasn't a trader and only worked in HR.
Questions d'entretien [1]
Question 1
Probability of the product of two die is a square number. Probability of x number of coins tossed, even number of heads. Probability of 99 coins with no information, last coin is a fair coin and the same question as above.
Maths probability questions in the first rounds getting harder and harder as you progress. If U have a basic understanding of the matter you should do fine in the first round but you might struggle later on
