Ventajas
The best thing from my own experience, is that they don't micro-manage you. They hire you to do the job and don't feel the need to hover over you to ensure you get it done. They provide a friendly open environment where everyone works together, without a defined hierarchy. You are treated as an equal by everyone, regardless of the initials that follow their name. They strive to provide a relaxed atmosphere and grant employees opportunities to have fun with their co-workers, whether it be at the weekly on site happy hours, to the amenities like, pool table, shuffleboard and Foosball or the full gym and basketball court. I also like the relaxed dress code.

Honestly, I haven't found any. I'll update my review should I stumble across something later.
