I Built My Friend an AI Interviewer That Remembers Where He Struggles

Developers created AI-powered mock interviewers for the Hacktoberfest Weekend Challenge: Build for a Friend. InterviewMirror focuses on identifying specific struggle points by asking critical follow-up questions to expose knowledge gaps. Another tool, powered by Gemma, operates entirely in the browser to help a software engineer practice verbal communication. These tools address the limitations of solo practice by simulating real-time conversations, providing immediate feedback, and challenging users to explain technical concepts out loud to a stranger.
