HireXai technical interview platform
HireX is a full-stack AI mock-interview platform that runs adaptive, voice-driven technical interviews, a live in-browser coding round, and produces deep, shareable evaluation reports. It works with zero API keys via an adaptive local engine, and becomes fully AI-driven the moment a single LLM key is added.

Key Challenge
Making the platform impressive with zero API keys while staying genuinely AI-driven when a key is present meant building an adaptive local engine behind the same interface as the LLM path. Streaming one question at a time and scaling difficulty to answer quality required careful session-state orchestration.
