The interview process is smooth, if you are in the next round, HR will usually email you in the next day. There are 4 round interviews and then the onsite assessment day.
I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY) in Sept 2025
Interview
Difficult, but heavily focused on technicals. Very smart people are interviewing, so you have to ace the technicals and then demonstrate a level of personability to have a shot. Prepare for a lot of math.
Interview questions [1]
Question 1
Suppose you are given the opportunity to bid for a treasure chest, which you know with 100% confidence to be priced anywhere between $0-$1000. If you bid equal to or above the price, you win the treasure chest (at the cost of your bid). If you bid below the price, you do not earn the treasure chest. Now, also suppose you have a friend who is willing to buy the treasure chest from you for one and a half times the price of the treasure chest (should you obtain the chest). What should your bid be?
