I have an onsite with Citadel HF coming up. They haven't given me any information whatsoever so it'd be good to know what the structure and questions on their interviews look like. I.e. coding rounds / system design / language specifics
Op, what is your profile - sills, languages?
Had terrible experience with them. Mine were LeetCode questions.
Same kinda. I got an interview request right after the hacker rank and then gave them some dates the same day. They didn't get back to me for a week and a half after all the dates had passed and then asked for new dates, only to miss all but one when they responded. Plus I kept getting tossed between multiple recruiters. Did the phone interview and I know for sure I killed it (answered question optimally, explained thought process, discussed lots of systems stuff, had a good convo with the interviewer) but they ghosted me for 3 weeks before sending a rejection email. It honestly felt like they just didn't want me at all because I know my phone interview could not have gone any better, very strange experience.
Expect mainly LC questions and one or two rounds of system design. If you’re applying for a specific team, there will be some domain specific questions as well
That's what I thought I'd expect, but when I had my phone screen with Citadel securities (not HF), the guy asked me multiple questions on how some of the std C++ lib structures and functions are implemented underneath. Also got asked specific low level networking questions none of which I was prepared for
Any good books on resources on answering those system design questions? Had a citadel inside before and the questions I got are not those you can find in grokking the system design book
