Python Backend + GenAI Interview Roadmap

A phase-wise, topic-wise checklist for Python backend and AI/GenAI engineering interviews. Each phase lists the topics to cover, the questions you should be able to answer, and a hands-on task to lock it in.

How to use this document

Work top to bottom. Phases 1 to 7 are the foundation; 10 to 11 are the backend core; 14 and 15 are what most modern interviews end with.
Tick the checkboxes as you go (- [x]).
For every topic, be able to (1) explain it in plain words, (2) write a short code example from memory, (3) name a real pitfall or trade-off.
