Pros
Compensation and benefits to an extent. Convenient location and facility, onsite gym, green field for sports.
Cons
Highly secretive and hypocritical culture with a dash of a far-eastern aptitude. Grinds good professionals down to either stressed out, overworked marionettes or political survivors. Attracts and harbors quite a bit of paycheck chasers and tech phonies. Processes frequently change and at the same time are as slow as the telegraph in the fiber optic era. It's hard to catch up and stay up to speed, esp for new hires. And of course politics. It has flooded everywhere. The ebay mothership advertises good values which unfortunately serve as a facade only. Usually values are walked over demonstratively after finding a convenient excuse.
