I applied through an employee referral. I interviewed at Citadel
Interview
Applied through a referral and got an automatic OA (Online Assessment).
Passed that round to get to a 45 min technical with an engineer. The questions seemed to be up to the interviewer and weren't super standardized. Next round was 3 straight 45 min technicals were similar to the previous round. The questions varied quite a bit from each interviewer. Some were more algorithmic based, design focused, or even systems focused.
Didn't pass this round.
