Bob Schieffer had a similar story where he was trying to get a job and went in to CBS's headquarters looking for someone high up to talk to. When he said his name was Bob the secretary responded that he was early but to go ahead and go in. He did an interview (more like good ol boys talk apparently), got the gig at CBS and ran out of there not knowing what just happened. Supposedly he found out years later that he had walked in before a Bob Shaffer (spelling similar, I may be wrong on it).

He had been working in steel mills for all of his teens, and after high school went into the Marines. After getting out of the marines, he went to get a job at GM on the assembly line.
He was well dressed and presented an air of confidence (thanks to the Marines), and so the receptionist assumed he was there for a managerial position instead of an assembly line position, and gave him the managerial application form.
He got the job, learned management and then moved on to other companies as a manager before finally starting his own company.
