Pros
Pay and benefits (except health insurance) are above standard mostly due to the fact people are hesitant to work for them. They are lured in on the idea that QBE has changed and reviews are outdated - they are not. They are accurate and current. A generous distribution of money is deposited in your 401k above and beyond the matching amount. My account grew nicely. Work life balance is good generally. Very little after hours work depending on your team though. Some teams are hammered hard after hours when on call. Work from home was allowed until recent management opinions waffled again to on-prem exclusivity. Managers and leads may allow work from home one day a week but even then you're assumed to be less effective than in the office. Office amenities are nice. Sun Prairie is undergoing a remodel and love/hate the new environments. If you want to work in a quiet cubicle, this isn't a place for you.
Kontras
To advance you are not qualified unless you are anointed by management. Your skills and past experience mean nothing. Technical leadership happens from the bottom up, guerrilla style, to make sure projects success in spite of inexperience and unskilled technical architects. If you aren't careful your work will be plagiarized and passed up to management without credit.
