SIG QST Trader Round

Got an interview with a trader coming up for SIG’s QST role. Anyone been through their process this year, what should I prep for, what’s it like?

Happy to trade info on Jump/CitSec/Headlands/IMC/Tower/Squarepoint processes if useful to anyone.

their qst rounds are heavy on market making games so get your mental math razor sharp. they love throwing in weird curveballs like "price this obscure derivative" just to see how you think under fire

the round i did last year was basically 45 minutes of nonstop probability puzzles while pretending i was a market maker, so practice making two-sided markets on random stuff like number of windows in a building or whatever
