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
