Share with the interviewer how you best learn new processes - do you prefer to go through training with someone or to be given step-by-step instructions and figure it out on your own. Also mention you would watch for any opportunities for process improvement along the way.

"I was actually asked to take over a few systems audits for the department last year. The person who was doing them had put in her notice and they were dispersing her workload amongst the team until a replacement could be hired. I was quick to agree to take it on, as I'm always looking for opportunities to learn something new. I asked the girl who was leaving if we could schedule some time to go through the process together before her last day, and I took careful notes of each step she took while I watched her navigate the audits. Once I was able to walk through it on my own, I noticed there were a couple of points where the steps could be combined and I was able to cut about 15 minutes off the total time it took. I also noticed there was one element of the audit we were missing (we weren't looking for part-time employees whose insurance needed to be stopped) so I asked my manager about it. It turned out that had been overlooked and we added that into the audits going forward."
