Overview

An AI interviewer that talks to candidates in real time (OpenAI Realtime over WebRTC) and, for engineering roles, runs a live coding round. Questions and JDs are generated offline with Gemini.

My part: the coding round — a Monaco editor with per-language persistence, and a Judge0 execution layer that runs submissions against sample and hidden test cases and scores by pass rate (Daytona sandboxes as an alternative provider).
