It's a huge international company, with all the institutional sclerosis that implies. IT and HR are mostly outsourced and difficult to interact with. Many of the internal systems are antiquated, adding a little friction to your day-to-day. The center of gravity is in London and Amsterdam, so despite their claims of being remote-friendly, the people in the office do have career advantages. The people you'll work with tend to be Dutch or German, which encourages a very traditional and process-oriented way of working.

Pay is just average & thus is the talent they attract, except for that acquired via acquisition. Being a market leader in a company that serves academia, it attracts controversy and has historically struggled to manage these well, so you may take a reputation hit among your academic friends.
