4. What does success look like here?
A responsible and very smart open question that covers a lot of ground. You're inadvertently asking about how employees are treated, internal processes, future opportunities for promotion. The answer to this will tell you a lot.
5. What is the company's approach to failure?
While it may seem to be a dangerous question, every company has had to deal with things not going its way at some point. The answer to this will tell you a lot about the company culture. Those in 'steady state' businesses may react like they have something to hide. Listen for positive responses – anecdotes about transformation, agility and flexibility.
6. What's your management style?
A key question. You'll have gone into the interview asking yourself whether your working style is a good fit with your potential future employer and colleagues. Listen out for a sense of this person's working style and see if it aligns with yours.
7. What are your expectations of this role?
For insight into what will be expected of you, ask this. A variation on a theme here is 'What would you like to see from this role in the first 30,60, 90 days?'. Or be bolder and ask 'What would you like to see from me in the first 30, 60, 90 days?' – I'm likely to take it as proactive, not presumptuous.
8. How does this role fit within the organization's broader strategy?
Lovely. Let's get down to business. A good back up question if you haven't got much out of the response to the previous question.
9. How do I compare with the other candidates you've interviewed for this role?
You may not get much back, but it's a brave question that acknowledges that no interview is a one-horse race. And if it is, you're either brilliant or it's a red flag!
