Technical Interview Prep

A complete, browser-based training system for technical coding interviews. Low friction, visible progress, and immediate feedback at every step.

Core features

  • 25+ algorithm problems across arrays, strings, trees, graphs, DP, and more — each with 5-level progressive hints, brute-force and optimal solutions, complexity analysis, and interviewer follow-ups
  • Guided problem-solving flow — an 11-step structured interview simulation from restating the problem through coding to reflection
  • Pattern recognition drills — identify which algorithmic pattern applies to a problem summary
  • Complexity drills — analyse code snippets for time and space complexity
  • Mock interview mode — timed, realistic simulations with follow-up questions
  • Flashcards & rapid revision — spaced-repetition flashcards covering core concepts
  • Focus Map dashboard — see your strongest and weakest areas with a single clear next action
  • Spaced repetition (SM-2) — weak problems resurface automatically at optimal intervals

Designed to keep you moving

  • Session modes by available time (10 / 30 / 60 min)
  • Warm-up rounds to build momentum
  • Sentence starters and templates to get past blank-page moments
  • Gentle nudges when you're stuck
  • Quick-exit bookmarking with instant resume
  • Streak system to build consistency
  • Keyboard shortcuts for every action

How it works

Everything runs entirely in your browser. No server calls, no accounts needed. Progress is saved to localStorage and persists across sessions.
