Pros
I have the opportunity to regularly interact with both senior management and individual contributors across the company and while I can understand some of the frustrations others have expressed, I can say for certain that senior management knows what's going on and has done a great job of adjusting the company to growing pains. From my perspective, this is the least political company I've worked at. People are truly helpful and responsive and if you take some effort to get to know them you'll find open doors. The team atmosphere is second to none and I completely disagree with people who say it feels like a cult. A cult is where people unquestioningly follow a charismatic leader. QlikView is the furthest from that. Differences of opinion is encouraged and doesn't result in career damage.
Cons
Meeting space and office space is at a premium but they are working hard to remedy that. Could we all get ultrabooks for our next laptop?
