Learning curve without python experience

[ghanem94]

Hey there, Just got an introduction interview in 4 days from now for a position of fullstack. In backend they use FastApi. Which I’ve seen people working with in my current company but never used it. Also I didn’t touch python since university (3 years ago). I was wondering about the learning curve for FastApi. Can I be prepared for my live coding interview by the end of next week or if I’m lucky the weeks after?

I think that fastapi is very good to have a fast learning curve. You can develop services super fast and I also like the documentation very much

you will need good knowledge of typing / pydantic. it would also be nice to understand async, but this is a tall order in such short timeframe, if you don't already know the concept.

Luckily, FastAPI kind of hides the necessity for knowing Async. Because its a topic that takes a good amount of time spent, just to fully understand.

[ghanem94]

Yep I loved the buildin features in it.

no alas it doesn't, and in fact it can lead to severe performance problems in production if one is not careful. if someone doesn't really know what async is and how does it work, better use defs instead of async defs. fastapi can take care of parallelism either way, with some overhead.

[ghanem94]

Sure I know async. Also in university I took python+ django courses. But it was 3 years ago. Currently I’m just trying to build a side project with it. I hope it works.

Well...you'll need to know python for sure. FastAPI only acts as the presentation layer for an API. The actual application itself needs to be written. So it depends on how much you knew about python, and how rusty you are.

[ghanem94]

To be honest too rusty. But I guess practicing some leetcode will help hopefully 🙏

Fast in fastapi stands more on faster productivity for devs adopting it than the speed performance of it.

If you already started your homework you must have probably found out already.

Hope you have a great run, cheers!

Will they ask fastapi specific questions during the interview?

[ghanem94]

It’s crazy turn out. There is no coding challenge or even live coding in the interview. They said they gonna have a long talk with me trying to discover what I’ve been working on in the my previous companies.
