LeetDuck: LeetCode on Steroids – AI-Powered Mock Interviewer for Realistic Practice

Summary: LeetDuck is a Chrome extension that integrates with LeetCode to simulate realistic technical interviews using voice interaction and AI feedback. It prompts users with behavioral questions, monitors coding runs, and evaluates spoken explanations against FAANG interview standards to improve communication and problem-solving clarity.

What it does

LeetDuck overlays LeetCode problems with a voice-driven interface that asks behavioral questions, reacts to code submissions, and prompts users to explain their solutions and complexities. It transcribes and grades spoken responses based on real FAANG interview transcripts, providing structured feedback.

Who it's for

It is designed for software engineers preparing for technical interviews who want to practice thinking aloud and improve verbal communication during coding challenges.

Why it matters

LeetDuck addresses the gap in traditional LeetCode practice by training users to vocalize their thought process, a critical skill often overlooked yet essential for interview success.
