This is a direct question that requires a direct answer. Remember, this will probably be verified through references from your previous companies. Don't fabricate or embellish because that can cost you the job.
If you've never run an auditing team, be honest. You can't lead a team when you're fresh out of college or have only participated in one audit on which you were the first line. Experience matters.
"I successfully ran two audit teams and assisted in over 60 total audits. You have to start from the bottom in this field, and I worked my way up."
"I've never managed an auditing team, but with my level of experience I don't think that would be appropriate as I wouldn't want to miss anything and put the company at risk due to my level of knowledge."
"I've managed several different auditing teams at the same time. I reached a level in my previous company where I managed four different audit clients at one time, so I had four different audits going on with with teams on each. Most audits have various levels of reviewers and different tiers of teams so it could get very complicated, but with the right organizational system, you can keep track of everything."
