DevPrep AI?

DevPrep AI was born from a desire to move beyond static coding challenges. It is a dynamic simulation engine that ingests raw job descriptions (JD) and spawns an AI persona tailored to that specific role. The system acts as a 'Bar Raiser,' conducting a voice-or-text interview, probing for depth, and generating a detailed feedback matrix. Under the hood, it leverages a sophisticated prompt engineering pipeline to prevent hallucination and maintain context across long conversation windows.
