Doing vs Learning

Recently a guy, say Mr. B. applied for a job in our company as an android app developer. As soon as he arrived in for the interview, his phone started ringing, and I allowed him to receive the calls. He received several phone calls during the interview session. After every next phone call, he’d tell me that some other company is calling him to join them. After he repeated the same thing twice, I decided to see what this guy has that I might have overlooked. I had made my initial judgment from his answers to a few of my questions related to android app development.
