Pros
Everything: Quality of work life; talented and inclusive teams; great work environment; extensive training opportunities; generous perks; better than average benefits; fulfilling work. This company goes above and beyond - they're great now, and still, they work daily at becoming even greater, foremost with a mind toward making ServiceNow an excellent place to work, and its products work for its customers.
Cons
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.
