The experience was quite intense with quite a few interviews in a short amount of time, in total I spoke to them about 7 times with a case study in the span of 2 weeks.
I applied online. I interviewed at IMC Trading in Nov 2022
Interview
Online assessment where you had to play 4 different games covering memory, reflexes, strategy, and problem-solving. An odd initial stage, but found the games quite enjoyable compared to roles that cover the usual boring Maths questions. Next was a video interview where you receive two questions with a short time to prepare, after which it begins automatically recording your response. First Q was about current market conditions, second was a Bayes Theorem probability brain teaser surrounding die, which wasn't particularly difficult, I simple was not adequately prepared for a Bayes question.
Interview questions [1]
Question 1
You have two die, one of which is 4-sided, the other of which is six-sided. Given that you have rolled a 2, what is the expected value of the second roll?
