Having onsite at Citadel soon for internship. What should I expect? Done around 470 LCs. Some people say they ask operating systems stuff and networking. Never really took those classes before. How should I approach about learning those or preparing for interview?

    After 470 LC, I’d say expect it to be a breeze. I don’t think they ask networking and OS questions any more... But everything is possible. One of my friends told me that all of his interviews were just conversations with no problem solving or system design. WTF.

    Interview is a joke. LC easy or medium for algo questions. They asked me a bunch of threading questions, dist sys, c++ vs java, and system design was a geared more towards to u know how to write maintainable code (exception handling, extensibility). You code on a laptop. Overall, not as difficult as tech company interviews

    Usually it’s LC and potentially system design type questions. I haven’t heard OS/networking questions for SWE but could get some concurrency problems (build a thread-safe x).

    I just had a phone interview with citadel securities. I was only asked networking, multithreading, and OS questions. One coding problem but that was based on low level implementation and not algos.
