People who apply to Google aren't desperate.

People already know Google exists and whether or not they want to work there. For most people (projecting here) the only recruiting Google has to do basically comes down to: We think you're good enough to have a chance.

For 99.9% of the companies this is not the case.

For example I like working at my current employer and enjoy the challenges compared to earlier employments. But looking at the job postings, I can't see that. It's generic crap about competitive compensation, challenging problems, modern technologies, a flat organization, etc.

If this job posting landed in my mailbox I would skip it. The only reason I applied for this job is because I was jobless and desperate at that time.
