What's your major? I wouldn't expect it to be that hard, they hire people from all different backgrounds, not just finance people. Being willing to bust your ass is much more important than being smart.

thanks man...my buddy works on their advisory side and said it was basic...
i majored in econ and finance im thinking it will be easy but i cannot afford to mess something like this up.... its just an assistant/associate role but they said within 3 years they expect the candidate to move into an actual equity sales role managing accounts and soforth

I have a bit of experience with these interviews. One time I was about five minutes into a second round interview and out of nowhere, the recruiter asks me what is "ten over fivefactorial." My dumb ass tries to do this as fast as possible so I blurt out "1/24" and before I could correct myself (answer was 1/12) she said that was all and they had no more questions. Be careful and take your time as accuracy counts more than speed.
The actual math was never difficult, you just have to know your probability and expected value. Here's a sample of the kinds of questions I have been asked in the first round for S&T positions: "You have a deck of 97 cards, numbered 197. The deck is shuffled randomly. Now I propose a game in which you draw five cards from the deck at random. If the cards come up in ascending order, I will pay you $10. Exactly how much are you willing to pay to play this game?"

What's the probability on the 197 card question? I'm not the most mathematically inclined person and can't figure out a good way through it. Do you have to treat it like an options pricing model or something?

The answer they look for is the ability to make the distinction that the actual numbers on the card do not matter such that their order is unchanged. So there is no difference between 1,2,3,4,5 (from a 5card deck) and 1,2,3,4,6 (from a 6card deck). In both instances, the cards are ordered in ascending order (as opposed to sequential order). In other words, you could draw five cards from a 97card deck: 1,15,23,72,91 and they are still in order. So now you can look back at the original problem with the 97card deck and draw 5 cards out at random. These 5 cards can now be considered to be a "new" 5card deck (and the numbers on them don't really matter so long as they are all unique). The probability of drawing 5 cards in ascending order out of any 5card deck is 1 divided by the total number of possible orders (5! = 120), thus the probability is 1/120. So, if you receive a payout is $10 once out of every 120 draws (on average), then you will want to pay less than $10/120 = $0.08 to play the game each time. No calculator was allowed and I was given a pencil and paper. Last edited by aut0sh0cker; 03042011 at 04:42 PM.
