Wincent Capital Management interview questions

1st round is two set of probability and statistics questions, each has around 30-45mins to complete, the difficulty is ok, all questions feel like variants of the Green Book questions. 2nd round is a 30 mins interview, 3 questions are asked but the interviewer will terminate the interview midway if he thinks you are disqualified for the position. Questions are hard and mixed of both combinatorics and probability categories, did not make it to the next round.
