Pros
Ability to work on some very exciting projects and with inspirational thinkers. Many people at the org are easily motivated simply by TED's mission ("ideas worth spreading").
Cons
The organization is riddled with cultural and structural issues from top to bottom. They are far too top-heavy and fail to invest in their people. Do not expect any career development, professional development, or room for advancement. No structured feedback whatsoever. And the management/director roles are occupied by people who entirely lack "people management" skills. The compensation is not competitive and the benefits (with the exception of healthcare) are far below industry standards. How a company that preaches work-life balance and future thinkers in business/work can offer their employees 5 PTO days is almost offensive.
