I'm interested in walking the quant path. Just how high is the bar? And would there be an equivalent project that would put a prospective quant to the top of the resume pile?

I've attached two pdf's on what you should expect. The latter was the take home an old company used to give quants as a test. If you can answer the questions on teh practicum then you probably have enough math skills to start as a quant. https://drive.google.com/folderview?id=0B1iikX5PwNx4d2dKQ3FTSWVRSDA&usp=sharing https://drive.google.com/folderview?id=0B1iikX5PwNx4d2dKQ3FT...

  Question 4 was fun :) Not sure what technique they wanted you to use, but it was easy to work back from the desired outcome, keeping track of the current IOU balance and the bet that would leave you in the desired position. I assume the early questions illuminate the general way of doing this. ==== SPOILER ==== Create a 4 * 4 matrix BET_m,n and a 5 * 5 matrix IOU_m,n, where m and n are the number of wins for each team respectively, and each matrix encodes how much is bet and owed after that many wins. Our initial constraints give IOU_0,0 = 0, as nothing is owed until a team wins a game. IOU_4,* = 100 and IOU_* ,4 = -100. It's hard to see what BET_0,0 should be starting from the start, so instead lets work backwards. If a team has 3 wins, and wins again, then the bet plus current IOU must equal 100 if it's my team winning, -100 if the other. IOU_3,3 + BET_3,3 = IOU_4,3 = 100 IOU_3,3 - BET_3,3 = IOU_3,4 = -100 Thus BET_3,3 = 100 and IOU_3,3 = 0 Our matrices now look like BET = [. . . . . . . . . . . . . . . 100] IOU = [0 . . . -100 . . . . -100 . . . . -100 . . . 0 -100 100 100 100 100 . ] IOU_3,2 + BET_3,2 = 100 IOU_3,2 - BET_3,2 = 0 So BET_3,2 = 50 and IOU_3,2 = 50 By symmetry BET_2,3 = 50 and IOU_2,3 = -50 Working along the m=3 and n=3 edges we get BET = [. . . 12.5 . . . 25 . . . 50 12.5 25 50 100 ] IOU = [0 . . -87.5 -100 . . . -75 -100 . . . -50 -100 87.5 75 50 0 -100 100 100 100 100 . ] In general, our constraints are: IOU_m,n + BET_m,n = IOU_m+1,n IOU_m,n - BET_m,n = IOU_m,n+1 Filling in through the middle BET = [31.25 31.25 25 12.5 31.25 37.5 37.5 25 25 37.5 50 50 12.5 25 50 100 ] IOU = [0 -31.25 -62.5 -87.5 -100 31.25 0 -37.5 -75 -100 62.5 37.5 0 -50 -100 87.5 75 50 0 -100 100 100 100 100 . ]
