"The most challenging problem I have encountered in my professional career was with my most recent employer. I had an incredibly important project that made up the majority of my annual budget. The client was challenging to work with as he was rarely available for comment, due to extensive international travel. I needed this deal to work out so, for the 6-month span of the project, I made my work hours reflect his time zone. This allowed us to communicate via Skype on a daily basis. This meant a fair share of late night and early morning calls for me! It was a sacrifice; however, I would do it again. I understand that sacrifices need to be made for successful outcomes to happen."
