The biggest challenge I faced at my previous job was its closure, of course. You know, we announced the closure and I was actually responsible for the closing of it. You know, reaching out to clients, reaching out to vendors, that sort of thing, making sure all of our ducks were in a row so that we could close on the projected close date. It was sad, it was so hard to do, but I approached it with the same level of professionalism and efficiency that I did with any other job.
