I built a free quant interview trainer (Optiver/Citadel style games) - looking for honest feedback

Hey everyone,

I spent the last few months building outcryarcade - a practice site for quant trading interviews. It has timed games for mental math, probability, market making, and stats, plus mock interview sims modeled on formats from firms like Optiver, Citadel, and Two Sigma.

You get 3 free scored runs a day with no account and no card, so you can try it in about 2 minutes.

Full disclosure: it's my site. I'm not trying to sell anyone here - I'm posting because recruiting season is kicking off and I want feedback from people who have actually sat these interviews:

1. Do the questions feel like the real thing, or too easy/too hard?
2. Which firm formats am I missing or getting wrong?
3. What would make you actually use this over grinding a PDF of practice questions?

Brutal honesty welcome. If something feels off about a sim I'd genuinely rather hear it here than have it mislead someone before an interview. I can't link but the website is OutcryArcade
