I got all type of questions where at that point in time where aroung reactive programming and webflux. Currently if hiring will open again the concentration of the question would be classical multithreading/concurrency, usage of virtual threads in java, applying SOLID principles, unit | functional | integration testing all of them against the code you delivered in the second phase.

A light bulb question. If you don't answer this you will be rejected, be prepared. :) Other interview questions are very easy if you have hands on programming experience. Funny part is in last round you will encounter light bulb question.
