This candidate detailed their extensive interview pipeline for a Summer 2025 SWE Intern position at Citadel, which spanned 10.5 weeks.
The process started with an application on July 3rd, followed by an **Online Assessment (OA)** on July 14th. The OA had two problems; the candidate got all test cases correct on the first and half on the second.
On August 7th, a **45-minute technical interview** was conducted.
This led to an invite for a **Virtual Superday** on September 12th, which consisted of three back-to-back 45-minute technical interviews.
Following the Superday, there were two **final round leadership calls**: one with Citadel Securities on September 19th and another with a team at Citadel (not Citadel Securities) on September 20th.
After a follow-up call on October 2nd, the candidate received an offer.
General questions from other users indicated that technical questions might include topics like OS and computer organization (e.g., caches, pipelining in processors).
