Pros
The atmosphere is highly dependent on your department and its management, as it often is, but as a whole the culture was good. Despite being a technology-based company, things were rarely cutting edge, The benefits were decent, if not great. During the pandemic, the company moved to fully remote while making as much profit as before, if not more. The Ann Arbor office moved to a hotelling model after the pandemic was lifted.
Cons
The first group I worked with (I maintained a website) was professional and mostly predictable. The second group was an underappreciated and understaffed team working hard to keep a decrepit data pipeline supplying a major product running. Work was needed on the infrastructure, but team members were too afraid of change to let the upgrades happen and the manager wouldn't press the issue. After the Clarivate buyout, a round of layoffs meant two members of our 6 person team (including me) were let go. I had heard they were going to augment the workforce with offshoring, but I don't know how that worked out.
