OA (math, probability, brainteasers, quick math) then a series of interviews all virtual
math, probability, brainteasers (3 - 4 rounds)
then one round with head of trading, another with founder
Video interview with trader very technical and very probability based. Expected to show where your answers come from/ how you got the answer. Kind of awkward but they help you with hints
Online Assessment with 19 Math Questions where you aren't expected to get the exact answer but get close to it. Then a technical interview with a trader. I believe after that would most likely be a recruiter interview and then either another trader and then final round or straight to final round.
Interview questions [1]
Question 1
Betting game (simulating poker). There are only 2 cards- an ace and a queen. You and your opponent get a card each. You can see your card but the opponent can't. You both have $1 in the pot. With what probability p should you raise $1 if you have an ace, and with what probability q should you raise $1 if you have a queen- given that the opponent knows your strategy (knows your probabilities)?
