Pros
Amazing products. Sharp engineers. Some sharp business folk, product marketing, product management, etc. Great location. Chance to really, really impact how computing is done in the future. VMware is the most important company you've never heard of, on its way to sitting at the table with Intel, Google, and Microsoft.
Kontras
There's a lot of leftover dead wood from when the company was an acquired backwater. Diane Green kept around a lot of people who were in over their heads (in PR, in field marketing, etc.) and unfortunately, those folks ended up hiring a lot of other folks like them. They are still around. This is changing, slowly, with incompetents being tossed out under the new Maritz regime. However, it's the poor hires that impact company performance at this point, and who frustrate, and block stars from actually getting things done.
