So, the biggest challenge that I faced with my last job that was prior to mine was when I was working at Cellular Cells as working in terms of like an inventory coordinator. And one of the things that kind of came up was that there was just a lot of phone, like a shipment of phones, essentially, that weren't properly allocated or tagged in our system. So what it ended up requiring me to do was to reach out to the phone manufacturers and also the shipper to make sure that there was insurance on all the actual devices, going through the actual like warranty claim with the insurance company, with the shipping company, with FedEx, and making sure that those phones were properly delivered. And when I found out that they weren't properly delivered, I had to go through the process with the actual FedEx of going through and getting those actual shipments reimbursed for the company.
