So - what questions do you want interviewers to ask? And where should the conversation go?
I'll start - when a backend/infrastructure person, they should ask me "What information do you need to design a backend for X/Y/Z? What technologies do you lean towards, and what tools/budget/personnel do you need?"
This should evolve (some would say devolve) into a discussion about budget, scalability, devops, tooling, skillsets, users, requirements, documentation, etc.
How about for your skillset/area?
Don't say it like a police interrogation. Do make it clear there's plenty of time should a candidate need it.
On time, never signal there's a fixed cutoff time until interview over. For the right candidate there shouldn't be. As a manager it's your job to be able to make time.
I remain unsure how I'd answer. The truthful one is "yes I am educable but no I cannot promise this kind of stupidity won't happen again"
