Pros: Free food, which is not all that great. A monopoly position in its market helps allow for massive wastage of resources (see below).

Cons: Innumerable. Huge bureaucracy, ritualistic, cult-like atmosphere, bizarre Big Brother monitoring everywhere. Does everyone really need to know where and when you badged in and out? Entire teams that do little to nothing. Regular need to tell managers to pi** off when they attempt to bully you. Mind-numbingly boring work. Early 1980s technology hasn't changed a bit. And lastly, now that the owner has returned, having exhausted his political adventure, it is like Odysseus returning to Ithaca, and there will be major lettings go, new joiners first.

Pros: You get to work with very, very smart people. The salary is higher relative to most of the other firms, except Google.

Cons: Very horrible training. You get fired if you don't have 80% in training, but the actual job after training is very good.

Pros: Nice office, fun people, access to the terminal, location, tada.

Cons: Lots of high-up managers lack technical knowledge.
