So, I don't think my job was very challenging. Maybe just the biggest challenge that you could say that I had to face was just everyone being on the same page when it came to the sales, when it came to delivering, just everybody being always on the same page, feeling, if there was any feelings of concerns or if things weren't getting delivered on time, it was my job to make it happen for them. So I believe that was really the biggest challenge because sometimes there's things that were completely out of my hands, but we had to make it work. We had to work with the client. We had to make the client happy. So that would be one of the biggest, that was probably one of the biggest challenges, but just communicating with everyone, making sure that everybody was in the same page when it came to every client's needs, I believe that made it so much easier to solve any issues that we came across. Just like I would always tell my old boss, I was always open to any critiques. If I did anything wrong, if anything didn't go as planned, if he didn't like it, I was always open for him to give me feedback on my performance.
