PrepMeBuddy
AI Interview Simulation & Dynamic Technical Coaching Platform
Explore the architecture and capabilities below.
PrepMeBuddy is an AI-powered technical career acceleration engine that conducts real-time multimodal technical interviews. It combines low-latency speech synthesis, semantic code evaluation, and LLM reasoning to simulate rigorous Silicon Valley engineering interviews with live actionable feedback.
The problem worth solving.
Software engineers preparing for senior technical interviews lack affordable, high-fidelity mock interview platforms that evaluate both verbal communication and live code execution with realistic interviewer personality traits.
Engineered around the work.
Built an ultra-responsive web platform utilizing streaming LLM agents, real-time code sandbox execution, speech-to-text semantic transcription, and automated rubric benchmarking across algorithm complexity, communication clarity, and problem decomposition.
