Have you had to discipline an employee or fire an employee? How did you handle that situation?

Don't say that you have never had to fire anyone; the question also asks about disciplining an employee. If you have no supervisory experience, you should say so, but you can also recall a time you corrected someone else's behavior, even if you were not their supervisor. Your answer should show that you can confront a colleague directly and respectfully while holding them accountable for not meeting expectations.

"Yes, I have had to discipline and terminate employees. I feel strongly that no employee should ever be surprised in a performance review, so I make sure to provide feedback, whether positive or negative, as soon as possible after the behavior takes place. If an employee is consistently not meeting expectations, I would put them on a performance plan where we set very specific short-term criteria they must meet to remain in good standing. I would meet with the employee frequently to give them the best chance to get back on track."
