Python Developer interview questions: the 8 to ask

1. 1.What is the difference between a list and a generator, and when do you use each?
2. 2.How does the GIL work and how does it affect threading?
3. 3.How do you structure a mid-size FastAPI project?
4. 4.How do you manage dependencies and virtual environments?
5. 5.Explain async/await and a case where it really helps.
6. 6.How do you test code that depends on a database?
7. 7.How do you profile a slow script?
8. 8.Which typing practices do you follow (type hints, mypy)?

Tip: for every answer, ask for a concrete example (situation, action, result). An answer without an example is worth half.
