What question should I have asked but haven’t yet?

Spend time before the interview thinking of something about yourself that is a unique selling point that makes you the perfect fit for this job. Try to tailor your answer to this question in such a way that you will be able to reserve this information for the end of the interview, so you don't draw a blank should this question come up. This is your opportunity to try to close the deal. It's always a good idea to have a card up your sleeve that you can pull out at the end.

Anything that's inconsistent with the rest of the interview will serve as a red flag. Put yourselves in the interviewer's shoes and ask a question they would've asked but didn't. Be appropriate and filtered.

"I would've asked me what I do to support the rest of my team and my team leaders. It's my job to make my boss's jobs easier. They need me to perform my job effectively so that they can concentrate on theirs. Therefore, as soon as I have a sense of what's expected of me after my first 30-60-90 days, I'll ask a slew of questions about what they need to do to get us to where we need to go, together as a team. Having a deeper understanding of what their job entails gives me a deeper understanding of what's expected of me. That way, when I go above and beyond, it's with a guided focus, where I'll lead by example, and set the pace for the rest of the team, getting us there faster. It's my job to make my boss's jobs easier, and this is how I go about it."

"I would have asked about my time management skills, to which I would have answered, 'I have outstanding time management skills.' I arrive to work early every day, prioritize my tasks effectively, never miss a deadline and work fast. I never bite off more than I can chew, and am clear when setting expectations."
