Exercises
| Level | Folder | What's inside |
|---|---|---|
| Warm-up | exercises/0_warmups/ |

01–06: iterator utils, LRU cache, retry decorator, bug hunt, KV transactions, log report |
| Middle+ | exercises/2_middle_plus/ |
07–10: Money, rate limiter, event bus, task graph |

Solutions are in solutions/ (same layout). Interview questions are in questions/middle.md and questions/senior.md.
Tips
- Don't open
solutions/until the tests pass. - Name the edge cases before you write code.
- When the tests pass, answer the Discussion questions at the end of the exercise. That's what interviewers ask.
