Recruiting Using Billboard Puzzle

A large billboard on Highway 101 says simply,

“{first 10-digit prime found in consecutive digits e}.com”

No indication of which company is advertising that.

If you follow through with the puzzle, Google appears and explains: “As you can imagine, we get many, many resumes every day, so we developed this little process to increase the signal to noise ratio.”

Rather clever if you ask me.

Having nothing to lose, I sent them my resume beta.

Here’s the email autoresponse they sent back:

Dear Problem Solver,

Thanks for taking the time to play with our little brain-teaser and for
sending us your solution. While you won’t find a confirmation of the
answer in this email, we did want to let you know that your message was
received and that we’ll be taking a look at it. If you submitted a resume,
we’ll be spending some time with that as well. If it seems like there
might be a fit with a position we have open, we’ll contact you within the
next few days.

And as for the answer to the puzzle, we’ll post the ads and the solution
on our site within a couple of months, after those who are a little slower
than you have had a chance to work on it a bit longer. Thanks again for
your interest in Google.

What I don’t understand is “the answer to the puzzle.” Didn’t we have to solve the puzzle to get to this point? Apparently not.
