  1. blackrock phone interview - dice roll

    Essentially, you need the following: E(N) = P(N < E(N - 1)) * E(N - 1) + (P(N > E(N - 1)) * (0.5 * floor(E(N - 1), integer) + 3.5)) P(N < E(N - 1)) * E(N - 1) This part means that if you roll less than the value of one less roll, you will roll again. (P(N > E(N - 1)) * (0.5 * floor(E(N -...
  2. How does raising interest rates help curb inflation?

    Think of interest rates as the price of cash. When they are low, cash is cheap; you need more cash to buy things. When you raise rates, cash is more expensive; you need less cash to buy things.
  3. 7.7 Jane Street interview question

    Here is a program I just wrote for Matlab to do this. I am JUST getting started Matlab, so I'm sure there are many ways to tighten up my code, but here it is. clear rolls = 4; % mutable sides = 9; % mutable sideposs = 1:sides; middle = mean(sideposs); expe(1) = middle; for i = 2:rolls for j =...
  4. Should I take GMAT a 3rd time for Rutgers MQF and GTech QCF?

    Don't you have to submit each score? In that case, I wouldn't see any value, but others may know better than I do.
  5. Didn't they set stoploss?

    This was across all their positions. They couldn't just set a global stop loss. Also, if the limits on the stop losses were getting blown through, they would keep missing the trade. Many of them also probably felt that they were losing because others were getting squeezed and being forced to...
  6. COMPARE Chicago MSFM Prep course vs. UCB Prep courses

    So far, I have enjoyed the program. The Statistics class is a little much and gets some complaints, but I think they are just packing way too much into one quarter. There is definitely a much greater effort being made in the way of career services; this had been a big complaint.
  7. COMPARE Chicago MSFM Prep course vs. UCB Prep courses

    Actually, the timing was funny. The acceptance letters came March 9, the day after the second bill was due.
  8. COMPARE Chicago MSFM Prep course vs. UCB Prep courses

    I'll answer this way... The math you'll need is not super difficult...if you had some calculus and linear algebra in undergrad, you'll be fine. For that reason, you don't really NEED a prep course for Chicago's MSFM. However, as I mentioned, if you enroll in the prep course, you will almost...
  9. COMPARE Chicago MSFM Prep course vs. UCB Prep courses

    As a participant in the Chicago prep course and a current MSFM student there, trust me on this...the Chicago prep course is a bribe to get into the program. Everyone who enrolls gets in. You will not learn anything useful. Edit: I'd like to stress that if you don't intend on applying to...

    I am almost certain this is incorrect.

  12. Probability Question

    I think the question is that you randomly flip 50 switches...for example, it could be 50 different switches, or it could be the same switch 50 times.
  13. Why did you choose Quantitative Finance?

    Was an options trader. Getting my MFE will hopefully open up many more doors for me.
  14. Overkill

    What is your reasoning? Don't you ever want to go out and earn an income?

    Not needed at all, but it never hurts.
