They might be getting confused with the person who blogged about their interview prep and ended up not getting an offer. I find it almost impossible to believe that Google would reject someone because they spent time and energy preparing for their interview process--they provide pretty detailed information about how to prepare and it's common knowledge.

Actually making it through an interview and getting an offer is much less common, for (what I'd consider) obvious reasons.

I interviewed at Google without any preparation and was not given an offer. I would have liked to have the time to prep, but I didn't, and I assumed I would not get an offer. I didn't do horribly, and I was encouraged to prep and return. I believe I'm good enough that if I prepped I'd get an offer--I simply don't have the time to jump through those particular hoops at this time, for better or worse.

No, that person didn't even get a phone call... Just a generic rejection without any interviews.
