What questions should you expect from a full stack interview?

Question

JavaScript

Frontend: React, Redux
Backend: Node, Express, MongoDB
What questions did you have about these technologies?

Answer 1

It seems to me that this is a rather rare combination in production, in any case, I did not receive a single interview offer.
In general, IMHO fullstacks work mainly for hire, i.e. freelance. A pure fullstack is rarely needed, and it's mostly PHP.
Returning to the question: they will ask for a portfolio. Perhaps there will be a test task, but the priority is the portfolio.

Answer 2

I will be banal, but there will be: questions as to a pure frontend and as to a pure backend.
