Yahoo

Yahoo has one of the best sets of internal tools to help a developer, and they should think about making these open source.

There aren't many other companies out there that handle the amount of data that Yahoo does, and no one else has been doing it for longer than Yahoo.

So if you are interested in Big Data, this is one of the best places to work for the sheer scale at which they operate.

The attrition rate is unbelievably high. The musical chairs that is the CEO's office is not helping matters. Senior management gets rewarded more for playing politics than for delivering new products/services. The technical leaders want to always play the safe game and just do enough to keep their jobs safe. Multiple teams are always working on similar projects, even after the huge layoffs. Teams are very insecure about other teams stepping on their toes, and there is not enough collaboration or communication between teams that are in different locations.

Make some strong decisions that will allow the company to be more nimble. Allow developers to work on their own projects, but instill in them the attitude of "fail fast" as opposed to working on a project for over a year before realizing that the project is futile.
