Go Track

Weekly Goals​

  • Machine Coding
    • Implement 3–4 additional problems in Go:
      • In-memory DB.
      • Pub/sub system.
      • Notification service (simplified).
      • URL shortener or task scheduler.
    • Emphasize tests, edge cases, clean error handling.
  • DSA
    • 2–3 problems/day.
  • Interview Skills
    • Practice explaining design choices.
