I applied through university. I interviewed at QUANTITATIVE BROKERS (New York, NY)
Interview
Five rounds, mainly covering two parts:
1. technical questions: probability & statistics problem sets and some high-level machine learning questions
2. insights on high frequency trading + a few behavioural questions
Interview questions [1]
Question 1
What is the expected cards to be turned over to see the first Ace?
Very rude and disrespectful. They don't value your time and they asked flawed questions. They show arrogans while they are not really good in statistics. Obviously they have a questionable hiring bar. Very bad experience.
