AT&T

• Decent salary
• Very flexible schedule
• Attractive bonuses
• 50% off all AT&T services

• Very little work to do.
• Have to come into the office when there is nothing to do.
• Feels like not contributing anything useful to society.
• Very little incentive to go above and beyond in the work because everything you do can be thrown out the next day.
• When not on a project, you're assigned trivial and boring work which I'd be embarrassed to even include on my resume.

I don't think you really value talent. Some of the smartest people I've met have left within two years for other jobs due to a lack of serious/interesting work. Giving BS and MS level engineers trivial work because there are no projects is an insult.
