Final interview ( 2 traders, three parts): Part 1 - Rapid fire multiplication and division eg 49*56.5, had to answer around 10 of these, be prepared to answer quickly and precisely, I was too slow - also remember the questions, I was asked multiple times if I could remember the previous questions Part 2 - Lots of Bayes questions, be prepared to manipulate Bayes rule, decks of cards, rolling dice etc. Part 3 - Final question was important he spent a lot of time of it and drilled me on logic behind each step, didn't answer very well but not too hard on reflection, understand this question and be able to walk through the steps: You have a chess board that is infinitely large, a horse can move 2 square either up, down, left or right and then another square perpendicular to the original direction - then they ask how many of the cases exist where the horse lands on a new square after 10 moves. They ask for a confidence interval and an actual number - I need a little more time on this one and it was difficult for me, he did say many people find this one tough.
