The interview pipeline for a Software Engineer at Cboe is designed to evaluate both theoretical computer science foundations and hands-on production engineering skills. The overall process moves systematically from an initial resume screen through a technical evaluation phase—often featuring a practical take-home assignment—and culminates in a detailed panel interview with engineering managers and team members.

Most candidates begin with a 30-minute introductory phone call with a recruiter or hiring manager. This conversation focuses on your background, technical interests, and alignment with Cboe's engineering culture. Following a successful initial screen, you will typically receive a take-home coding challenge centered around real-world domain logic, such as building an order book, parsing proprietary market data files, or aggregating trading metrics.

Candidates who clear the take-home challenge move to the final interview stage, which is commonly conducted as a multi-part virtual panel or on-site session. This stage consists of back-to-back technical and behavioral rounds with team leads, senior engineers, and department managers. You will review your take-home solution, work through live coding or whiteboard problems, discuss core computer science concepts, and answer behavioral questions about past project experiences.

The process chart above highlights the standard technical progression from initial contact to final decision. Candidates should treat the take-home assessment as a key milestone, as it serves as the core foundation for subsequent technical code reviews during the final panel rounds.
