I was tested on basic trigonometry knowledge which I never prepared for. But since I am solid on math that was not an issue for me. Another difficult question was that I was presented with two teams with identical settings of a competition and both teams are very smart people and I was to help team A to win over team B. Initially I was puzzled as how could one team win over the other if they have everything exactly the same. Comes out the question is to adopt a strategy that gives a team the best chance to win, but not necessarily win it. Once that is clarified the answer is easier.
