Kontras
There are none that I recognize. This is a company with a culture developed for, and centered around, its employees, from what I see. They give a lot; and still, they continue to seek to give more. It's amazing how generous this company strives to be in all areas. They listen, listen, listen to customers and employees, and hugely importantly, they respond with significant action. Employees certainly feel empowered here - though a huge company, it feels like a startup, with the ability to take ownership of developing great products. I couldn't have asked for a better company to land at.
