The technical interview consisted of a variety of questions on pricing, Fixed Income, numerical analysis. One question was: You are at the horse racetrack. Four horses are racing. Betting on any horse costs $100. Betting on the first three horses pays off $400. The fourth horse pays off $399. If you can both take and "write" bets, what is your strategy for riskless profit?
On the cover letter, a game theory problem with the problems. A multi-player game where all players play optimally and you have to find out what these optimal plays are given the settings in the questions. After, a general cognitive aptitude test which, if you respect yourself, you'll decline to do and move on to another company.
