Interview
After submitting my resume online, a phone call was set up between me and an HR. After that I had 3 rounds of phone interview with full time traders, and the questions are all related to probability.
Interview questions [1]
Question 1
If you randomly pick a 3-digit number, what's the probability that all 3 digits are even numbers?
Many rounds of brainteasers, some of which are more rapid fire in nature and others which require you to flesh out a detailed answer to a complex problem. Be well rested and well prepared!
mostly maths probability questions - a lot of conditional probability, relatively easy in the first round, but you need to think out loud - you need to be really fast
4 rounds in final. The first one is market making of cards. The rest are especially designed games. The interviewer may ask added question along the playing of the game
