HOW TO MAKE VIRAL MARKETING THROUGH HIRING FOLKS?

More and more I see this simple & effective viral marketing example: job ads as if a company is hiring folks. What happens? 'Join us', 'Recruitment', 'Vacancies', 'Career' - all this buzz is passing on from one guy to another.
The fresh example is the site of Microsoft Israel R&D Center.
Another example is about Google. In 2004 Google Labs published so called GLAT - Google Labs Aptitude Test. Readers were asked to mail in their answers and promised that they would be contacted by Google if they scored well.
The declared reason was to attract high quality people into their ranks. Actually, it was a clever viral marketing which generated a lot of interest.
How does it improve the company PR image?
1. The public gets the idea that the company (= Google Labs, in this case) is hiring only very clever folks.
2. The public gets the reminder that the company is on the map.
3. You get much buzz, interest and involvement about this point.

Now I remember one example more. In September 2006 the Shin Bet (= Shabak, the Internal Security Service of Israel) launched its first-ever public recruitment drive. The employment campaign was targeting computer programmers.

The viral marketing example for brains, intellectuals and know-it-all guys is declare that you are hiring folks.
