Prós
You will enjoy Unity if you love corporate politics and big egos. If you enjoy useless meetings, you will also like it here, because they are constantly in a state of planning, and never reach the hard part - execution of the plan. If you don't like your team/manager, just wait 6 weeks and you'll probably re-org anyways and start the cycle all over again.
Contras
Self-important and yet totally incompetent middle management. I literally couldn't tell you one thing that my manager produced or stuck with for more than 3 weeks. Technology Org steeped in toxic, clique-y culture. Very little career growth, and it's based on who your manager is (gatekeeping). Totally siloed and operationally dysfunctional. Not interested in any new ideas or hurting anyone's feelings which become major blockers to innovation and progress. Their disjointed product/website strategy reflect what Unity looks like on the inside - teams & systems that don't talk to each other, massive amounts of duplicate work, data all over the place, engineers and egos dictating business decisions, lack of transparency, and the most impressive non-answer answers from leadership I've ever seen.
