So everyone just reads the webpage, the interviewer gets the answer he expected. Not sure how that makes the developer better at his job. Sure they took an hour or so to read the webpage, but does it in any way matter?
(Actually one company I applied to recently did the opposite - they had a fake webpage with minimal detail - I am not sure if this was to catch out bullshitters. Anyway, when asked what I knew about the company, I was honest and said I didn't know much. The job didn't go ahead in the end, though the guy said he was impressed with me at the end of the interview).
