So, working at FedEx Ground as a quality assurance agent, we daily had to take calls with customers, a lot of times angry customers, and it was our goal to satisfy their needs and make sure we got them their packages. Every single day, I did my best to exceed those, and most days I was successful. As you can understand, there are a lot of different ways to cope with a frustrating encounter, and I think that was probably my biggest challenge, and it's a positive challenge for me, trying to overcome every single bit of adversity thrown my way, so I would definitely go with that.
