In my country they recently opened a Undergrad in financial enginering and i was wondering what education should i pursure. Should i do just an undergrad, should i do undergrad in math or stats and then an mfe or should i do an undergrad in fe and then an mfe. Would really like to hear your op on this.

      well , big firms often like to hire more math/stats/cs grads and sometimes physics and some engineering(civil , chem , ...) because they got the quantitative skills needed for this kind of job, i've seen some MFE graduates and they did get hired by some mid firms , but if you're aiming for top firms just take more cs and math classes and stay away from economics ones , and do a masters in statistics or cs or any quant major

      You can still get internships in your masters/pHD - these firms hire across the board I'd say look into competitions held by firms along while making one really in depth project that showcases your interest. From there it's simply practicing questions on the site and competitive programming (if you're going for quant developer) Hope this helps :)

    • @QuantQuestionsio
      @QuantQuestionsio Месяц назад

      My best recommendation is build out a project that shows your interest in quant finance, I'd even put it above my professional experience on my resume to highlight it. Here's an example: Statistical Arbitrage Project - it'll go from strategy generation, data sourcing, signal construction, backtesting, performance evaluation, weighting, optimization of strategy, etc -- this would be a bigger project, but depending on your timeline you can make a different one. Another idea is to try placing in a firms competition, some friends of mine did quite well in IMC Prosperity - other firms definitely have similar competitions. If you're aiming for Quant Developer - another idea could be focusing more on competitive programming, (code forces red is a good goal) Goodluck!

    • @QuantQuestionsio
      @QuantQuestionsio Месяц назад

      I mean you almost got it - if your friend must choose between 40-49, then if your 39 no matter what your friend picks he will be in this range Don't beat yourself about that though your thought process was correct, just practice more on quantquestions.io and that'll help to build your confidence. Some problems tend to have patterns to them, so even if you didn't get this problem, similar problems will now become easier. Good luck and don't give up!

      yes, to get ur friend to get a number between 40-49, you end your turn at sum 39, so that his range of sums is 40-49. keep doing this downwards, to get him to 39, you end turn 28, 17, 6

    E = the value of the first roll is strictly less than the value of the second roll. = e1 E complement = the value of the first roll is strictly greater than the value of the second roll (OR) the value of the first roll is strictly equal to the value of the second roll = e2 V e3 P(e3) = 6C1 * 1 / 6C1 * 6C1 = 1 / 6 By symmetry, P(e1) = P(e2) e2 ^ e3 = phi => P(e2 ^ e3) = 0 P(e2 V e3) = P(e2) + P(e3) - P(e2 ^ e3) = P(e2) + P(e3) By LOTP, P(E) + P(E complement) = 1 P(e1) + P(e2 V e3) = 1 P(e1) + P(e2) + P(e3) = 1 P(e1) + P(e1) + P(e3) = 1 2 * P(e1) + P(e3) = 1 P(e1) = 0.5(1 - P(e3)) = 0.5(1 - 1/6) = 0.5(5/6) = 5/12.

    Imagine the software that could have been built if the amount of energy put into trying to beat the market was re-directed into other projects. I hate how powerful money is honestly.

      But these industries create huge demand for highly distinguished problem solvers, and select them based solely on merit - with highly abstract transferrable skills into any STEM domain. If it wasn’t for these huge rewards, what else would motivate millions of scholars towards computational sciences? I agree money is too powerful, but in terms of pondering efficient allocations of capital, what about the billions spent into the entertainment industry? The effort gone into hosting sold out Taylor Swift concerts, Superbowl, Champions League, K-pop, and Bollywood, for I’d argue those costs create less value for society than even the investments industry. My point is, the best synergies/productivity happens when we let people do what they want to do, and let people pay for it… For we all apes afterall… So there will always be stupid spending, humans love singing women and wine. More importantly there will ALWAYS be conflict, and more fundamentally competition over finite resources, thus we have geopolitics, and that’s all business and money. If you want to solve this big money problem, we need to have world peace; or world domination.

      Maybe it says something about how relatively important beating the market is. So this would imply that efficient capital markets are very important for a modern economy.
