Pros
Excellent colleagues at the team level, and lots of great team leads. My team was easily the best part of my time at MW. Great WLB. The offices are very nice if you're fond of going in. Work is interesting if you're on a specialized team or if you're lucky enough to get to work with newer tech. Stakeholder dividend is nice, but equity would be nicer.
Kontras
Core values applied on a "rules for thee, not for me" basis by upper management. Despite proclaiming a "rational workplace" the rank and file were never given any reasoning for why they're required to work in the office while plenty of senior leaders have decided they themselves get to work fully remotely. Career progression is slow, based largely on tenure rather than performance. Pay could be better. Rent is rising faster than compensation in Massachusetts. Lots of teams stuck on older tech because "that's how it has always been done, it's too hard to change things now"
