Pros
They are growing at an immense pace so it keeps you on your toes. There are endless ways to continue learning with their fantastic Center For Learning and Innovation that provides a broad array of courses, certifications etc. to keep your skills sharp.
Cons
They talk about work-life balance but aren't really committed to it. In HR especially, there is an expectation to always be "on". Their turnover in HR and in general is pretty high. In the time I worked their they over 15 people left the HR department- none of which lasted much more than one year and a half. Leadership is condescending, malicious and discriminatory. Don't worry to move up the ladder if you aren't part of a certain clique. Raising employee relations issues only results in retaliation even though they claim they encourage employees to speak up.
