I don't have any first hand knowledge ... never worked there myself, but their reviews over glassdoor, comparably, and linkedIn have been pretty consistent over the past decade. The few staff members who have gone out of their ways to contact us ... backed up the reviews. Even though I have zero interest in actually ever working there, I keep track of their employee reviews, blogs, githubs, academic journals, patents, and job offers ... to keep better tabs on what technologies and projects their programmers are currently working on or are looking into.
Having such second / third hand knowledge of what is coming down the pipeline is valuable to myself and DM, so we know what to prepare for and what technologies to study.
