What is the main obstacle that prevents norville Barnes from easily landing his first job in the big city?

I think the answer is his inexperienced. The business graduate was first assigned to the mailroom of his current company. However, because of the death of the founder and president of the company, Barnes was hired as a temporary president of the company. Many people believed that he was naive and incompetent but they were very surprised at how Barnes was able to make the company boost its profit.
