Lots of analytical tests, lot of arithmetic math and puzzles and logic problems to solve, one of the most difficult interview processes I have partaken in, would recommend doing lots of mental math to prepare
Interview questions [1]
Question 1
What is probability of landing heads on three coins after flipping them 10 times?
First round interview with HR, then a call with a trader for first round. Then a superday with a trading game. Trading game was relatively simple just practice mental math
I applied online. The process took 2 weeks. I interviewed at Belvedere Trading
Interview
OA -> Technical interview with a trader. Asked about probability, mental math (think 2 digits), and estimation questions. Didn't make it beyond this, probably got too much help from the interviewer.
