I applied online. I interviewed at Citadel Securities in Nov 2018
Interview
received a coding challenge in a few days after applying, and scheduled an interview in about a week. I did not do well on the coding challenge, so I was surprised to have a phone interview.
Online assessment first with around 3 questions. Then 3 rounds of technical interviews + 1 round of behavioural interview. I failed at the behavioural one. Technical interviews can range from leetcode style to system design.
One leetcode question that you have to talk to the interviewer about, about medium difficulty, the problem is on codesignal and you talk through it. Nothing too different from other interviews
I applied online. The process took 1 day. I interviewed at Citadel Securities (New York, NY) in Jun 2025
Interview
Hackerank OA, two leetcode style questions, med-hard difficulty. Full-scored on OA but didn't hear back for in-person interview prolly cuz it's auto sent, and I didn't pass the resume screening.
