DSA Life Simulator: coding interview prep that plays like a game

Interview prep, but it fights back. Practice data structures and algorithms in a story world of company-themed districts, earn XP, keep streaks, beat boss battles, and take AI mock interviews with company-style interviewers. Free to start.

How it is different from LeetCode and HackerRank

  • Company districts: problems grouped by what FAANG, Microsoft, Oracle, Salesforce, Adobe, Stripe, PayPal, Wise, NVIDIA, Tesla, Qualcomm, Accenture, TCS and Infosys tend to ask.
  • Cinematic problems: every problem is a real engineering scenario at that company, not an abstract puzzle.
  • Game progression: XP, daily streaks, leaderboards, unlockable districts and boss fights.
  • AI mock interviews: voice or text interviewers with company personas, follow-up questions and a hiring-style report.
  • Code Review: find the bugs in a teammate's pull request, or fix AI-written code with an AI copilot and prove it with hidden tests.
  • Multiplayer: 1v1 speed coding, bug fix battles, college battles, clan wars and tournaments.
