This amused me today from a friend of mine who noticed this.  A job application on the Google website for the "Executive Assistant to the Executive Director, Google.org - San Francisco"

Check out point 3 from the mandatory job qualifications:

Requirements:

• 5-8 years administrative experience in a fast-paced, high-tech environment; non-profit experience is a plus.
• BA/BSc degree from a top-tier university.

• Proven mastery of Office applications, including Word, Excel, PowerPoint and Outlook.

• Interest and experience in using technology to improve work efficiency.
• Interest and experience in interacting with all levels and departments within a company - to include working with several field offices, domestic and international.
• Exceptional written and verbal communication skills
• Strong organizational skills, detail-oriented, and the ability to handle multiple priorities.

The implication seems clear - if they have "interest and experience in using technology to improve work efficiency" they'll need to be Microsoft Office experts.
