AI Interview Coach for LeetCode

About

AI Interview Coach turns every LeetCode session into a realistic mock interview — right inside the problem page.

HOW IT WORKS
When you open a LeetCode problem, click the blue "C" button on the right edge of the page. The AI introduces itself as your interviewer and asks you to explain your initial approach.

From there, it coaches you exactly like a senior engineer would in a real interview:
• Asks one focused question per turn — complexity, edge cases, tracing, design trade-offs
• Never gives away the answer; guides you with Socratic questions
• Reads your code directly from the Monaco editor — no copy/paste needed
• Detects your LeetCode Run/Submit results automatically and feeds them to the AI

When you're done, type "done" or "finished". The AI gives a structured evaluation:
  ✓ Correctness
  ✓ Time & space complexity
  ✓ Code quality and style
  ✓ Edge case handling
  ✓ What went well / areas for improvement
  ✓ Hiring recommendation: Strong Hire / Hire / No Hire / Strong No Hire
