High School Student’s Early Approach for Brainteasers

Hey y’all! I’m currently a high school senior that is looking into investment banking or a related finance role. I started out as pre-med and changed my decision due to thinking I’m more “fit” for IB.

Well I woke up this wonderful morning and discovered brainteasers that are asked in Investment Banking interviews. I immediately got sucked in to these endless threads and realized most of them want to make me shoot myself. HOW THE HECK DO Y’ALL calculate these in your brain??? I am literally feeling so overwhelmed I mean these brain teasers (most of them) are pretty difficult and having to answer them on the spot is genuinely just idk.

What can I do to “train” my brain from now on to prepare, or any other preparation tactics you can think of? I don’t want a goddamn riddle to be the reason I can’t go into this field.

Or should I just go back to medicine and just memorize stuff lol jk .

 

I have never been asked a brain teaser in an IB interview. I only got asked them once at a sophomore summer interview at a hedge fund. Pretty sure they are no longer standard questions. Traders might still get asked them tho

 

honestly just read through as many as you can. most people know the brain teasers, or at least the basic set up of it, beforehand so it’s less of figuring it out rather than just having been exposed to those types of questions beforehand. either way, don’t worry about it you’ve got years ahead to learn something that’ll probably take a week max
