I’ve got contacted by a recruiter to start Citadel SDE interview process, I’m told there will be a phone interview round, then on-site full loop.
Anyone interviewed with Citadel before? What questions do they ask? Do they have system design? Behavior questions? Are coding questions just leetcode?
If you're in a front office role (quant, or low-latency HF swe), then Citadel is awesome.
As a pure SWE, it's not a great place. Joining Citadel as an SWE from FB is a bad career move IMO.
The problems you'll work on will be significantly less challenging than at FB. The caliber of your peers will be much worse. And your exit options will be limited if you decide to quit finance.
You may get a short-term bump in TC, but you'll be worse-off in the long run.
