Multi part interview, started with online mental math assessment, 80 questions in 8 minutes. Simple 2 digit multiplication and basic probability questions followed. Over all with preparation not that difficult, but slightly tedious.
I applied online. The process took 2 weeks. I interviewed at Optiver (Amsterdam) in Dec 2023

Interview questions [1]
Question 1
Player A has one coin, player B has two coins. They play a game and bet a coin each. Player A has probability of winning the game p = 2/3, and hence player B probability q = 1 - p = 1/3. What's the probability that player A is gonna win overall (and hence player B goes bankrupt)?
