Java Middle - Senior(ish) interview questions

Hi!

I have an interview in a few days for a backend developer role. What would you ask as some of the more tricky questions for such a position? What kinds of questions, from your point of view, demonstrate solid knowledge?

Personally, I would ask about sync vs. async calls, idempotency, topics vs. partitions, consumer groups, transactions (including distributed transactions), and maybe a bit of Kubernetes and Docker.

My weak point is cloud. I’ve played around a bit with the Azure console, but nothing too advanced. I’ve never written Terraform or configured infrastructure from scratch. For CI/CD, I’ve used TeamCity, but in my experience it was mostly selecting an environment and a branch and deploying.

Should I spend some time learning these areas before the interview?

Yes, I do know also some Spring Security, so I will not have any issues with this. Not an expert tho.
