Purely theoretical and methodological research with the potential for important applications is also published. The papers published present useful theoretical and methodological results with the support of interesting empirical applications. They cannot be bothered with my thought process! But certainly that is not every interview.Review of Quantitative Finance and Accounting deals with research involving the interaction of finance with accounting, economics and quantitative methods, focused on finance and accounting. I've definitely had interviews over the phone where the interviewer is likely playing candy crush on his or her phone and barely listening until they hear the answer. It might also have to be in the form of a video explanation of how those 1-4 core concepts were necessary in formulating the answer. Or questions that require things like n-1 or n-k-1 or n-k, I could see the explain your reasoning concept work nicely there.Īnd implementation wise, after a question, I can prompt the user with 1-4 follow up questions and 1-4 explain your logic/reasoning deep dive questions. So if you integrated between pi/2 and inf, this "explain your reasoning" question would ask you type out why you chose that vs pi to inf or 0 to inf or whatever. For every problem, including the one you provided above, I'd need to select the say 1-4 key concepts or parameters selected behind solving the problem.

I do think this is doable just will take a lot of work.

And I do like the "explain your reasoning" follow up questions idea as well.

I currently have the concept of "related questions", so the "follow up" question is a more narrowed version of questions with higher probability of following a given question compared to these related questions. It is sort of similar to feed back I had from a friend regarding my categories of math vs stats which can be blurry at times. Even the most basic stochastic calc question is impossibly hard if you have never taken a course in it. I think those categories need to be relative to say the average person who has studied that topic. I haven't yet put too much thought into the easy, medium and hard but I will add it to the to do list. Thanks for the feedback and thoughtful response. Overall it looks pretty good, with some publicity I think it could actually become pretty popular. A reference to Wald’s equality or a derivation of the same logic would probably be needed, and that’s hard to replicate through a site like this but it’s something worth thinking about.Īnother thing is that there are typically many follow up questions and modifications that interviewers will make to a problem, but this seems easier to implement. A person with really bad rigor and pattern-matchy intuition might say e/2 and cite the fact that the EV of each draw is 1/2, but most interviewers wouldn’t be satisfied with that alone even though it is the correct answer. The answer turns out to be e, and then the follow up is typically to find the expected sum once you’ve exceed 1. For example there’s a common question where you are asked to find the expected number of draws from so that all your draws have a sum > 1.

The other thing that makes this a little difficult compared to Leetcode is that interviewers usually grill you quite a bit on your reasoning, and this is hard to train through a Leetcode-esque site. I think the questions are a little on the easy side eg the “Hard” questions that I was able to read or recognize from the name were usually phone screens warm ups at some firms. The site design is actually quite nice I’ve been wondering why a Leetcode equivalent for quant questions hasn’t been made since the probability questions tend to be similarly studyable. Any additional practice problems would also be greatly appreciated! Specifically, I know I need help on brain teasers, market-making games, any extraneous math concepts they might ask, any probability that might not be in the two books I mentioned, and I guess any other topics that I might not have already mentioned. For algorithms, I'm just planning on doing Leetcode (I can be hit/miss for FAANG-level companies now, but I know quant companies ask harder questions on average). Also planning to grind the mental math sites too but closer to my interviews as I found the speed typically falls off if I don't keep doing it consistently, while it only takes a week-ish for me to ramp up. I'm going to go through Heard on the Street and a Practical Guide to Quant Finance Interviews and was wondering if other people know of other resources.
QUANT FINANCE FREE
Could we start a list of resources for preparing for Quant Interviews? Have a little extra free time due to Corona now and wanted to get a head start for the Fall.
