What questions do you, as a candidate, ask at interviews?

My questions to the hiring manager:
1️⃣ What is the most important working unit of an architect?
Mumbling in response shows how deeply operational inefficiency has wrapped the architecture function in the company.

2️⃣ How do you plan to evaluate whether the person hired for this position is successful?
“Everyone should be happy” shows that the company has no clear understanding of what effective work means and that politics dominates.
Mumbling means the company doesn’t really know why it’s looking for an architect.

3️⃣ What are the top 3 pains/problems that irritate you most in this area right now?
The answer shapes my plans for the future work - these are exactly the problems I’ll fix first.
If they can’t answer, the interviewer is inexperienced in this role and I should talk to their manager.
If they say there are no such problems, they’re looking for someone to do trivial work. Usually, expectations (and salaries) there are below market level.

Now it’s your turn - what are the most important questions you ask?
