I would be pretty shocked if you are even remotely on the right track.
I did over 50 interviews of technical candidates while at Google, and 6 of them were phone screens.
One of them tried this on me, so it definitely happens. Two of them tried the "look things up on the Internet to answer the question" trick.
Personally, I would have had him drive the hour and a half from Boynton Beach to the Miami MarCom office, and interview from there. I don't recruit directly since my pre-Google/pre-Apple/Pre-IBM days, but if you are acting as a recruiter, one of the best gauges of a candidates personality is the front desk person's opinion of them. I can't see a recruiter passing on that information.
Shields should have gone up from the they-contact-you-because-you're-desirable-then-they-phone-screen moment. If they want you, they'll call you in, and if they *really* want you, they'll fly you to Mountain View to get a full team on your interview.
PS: I was 5 minutes late to exactly one of them because the bike I was riding to the building broke down. It would be interesting to hear an explanation of why the recruiter was not on the line with the person at the appointed time, and telling them of the schedule change and asking if it was OK with the candidate. For the on-site I was late for, the last interviewer stayed with the candidate until I got there. At a full 10 minutes of no-show I would have been substituted.
