Difficult interview
Application
I applied online. I interviewed at Jane Street in Jul 2025
Interview
I was asked to solve a couple maths problems and show working and ask for hints if stuck. The experience was greatly positive overall and the interviewer was highly supportive and offered clarification and assistance.
Interview questions [1]
Question 1
You are invited to partake in a challenge with an 8-sided die. Here's the setup:
Roll the die once.
Decide whether to accept that score or risk a second roll.
If you choose to roll again, your score is the combined total of both rolls.
If the sum exceeds 8, you "bust" and score zero.
Given these rules, outline the optimal strategy after the outcome of the first roll. Specifically, should you risk a second roll or keep your initial score?
3 online interviews before the final on-site one. The whole process is around a month. Mostly consists of probability questions. Poker chips are given in the final round to bet on certain decisions.

Figuring out the strategy of a computer opponent in a turn based game and devising a strategy against them.
zuerst basic fragen zum einsteigen danach ziemlich schnell weiter mit theoretischen fragen. anfangend mit einer eher leichten frage und langsam drauf aufbauend mit neuen Bedingungen. insgesamt war es meiner meinung nach eine gute Erfahrung.
