Prop Trading Interview Guide - Putting together an e interview
Hi everyone,
I am currently in the process of putting together an interview e-guidebook specifically for those who would like to land a trader position at any of the first tier proprietary trading firms (Jane Street, SIG and the likes). It is going to contain probability, coming up with algos (not coding), guesstimation and brainteaser type of questions, with all of them being actual interview questions.
Each solution is provided step-by-step and I plan on adding tips on how to tackle certain kind of problems as well (how to answer when asked for confidence intervals, market making, how much would you bet on your answer to be right, etc.). I'm not sure but I'm also thinking of having a section which would explain how to apply important theorems (Fermi, Penney, etc.) to the usual questions.
I opened this thread because I am offering a rough cut (so it's incomplete now but once it's done you'll get the full book) version at a 25% discount rate for any WSO member. I would like to make sure that there is a demand for this before going forward and would also like to collect a few reviews/feedback on what else you would like to see in the book.
So if you would be interested in knowing more about it, let me know in PM. By the way you wouldn't have to pay anything upfront - you just take a look at the rough cut version and then decide whether you'd like to pre-order at a 25% discount rate or not.

Looks good, you should name it "Every Stats 101 text ever"
Looks like you stole those out of a basic college level probability solution manual
Nah, the sample questions you see were all asked during the 2nd-3rd rounds at Jane Street so I'm not sure if these are constituted basic college level difficulty - even so I see nothing wrong with preparing for these questions in a targeted way (instead of going through random college books which is certainly useful, just not as effective).
When I was doing Jane Street interviews they didn't ask anything you couldn't do with what my prob1/stat2 classes taught. Same goes for most of those questions, although they're obviously still good practice (some of your solutions can be simplified though... #15 O.o).
In my experience the rounds are more about consistency than anything else. At least that's what screwed me up - mess up on the mental math while doing your tail risk calc and you will get so incredibly boned...
Yea since a coin has a Bernoulli distribution, 15 would just be np (60.5) = 3. A tree is definitely not needed for that question.
Fair points, thanks, going to update these.
Your solution to problem 11 is incorrect.
By the way, what is your experience? Obviously you don't work at one of those trading firms. Did you interview at these firms yourself? Did you make the final round of the Jane Street interview?
Just go to glassdoor
@polymorphic123 phd in a quantitative field, left academia years ago, now work at a local prop. With JS I made it to the 3rd round (being interrogated over the phone is harder than I expected..); going to look into 11 (It's a draft anyway so solutions are not final yet).
@QWEigniteR there will be a more convenient way to do that -> this guide.
