Toxic work environment, no accountability or clear direction from management; instead, a blame culture is encouraged. Incompetent and arrogant management (Dutch company). Cheap at raises and bonuses. Career advancement is near-impossible unless you are a white European male. Turnover rate is exceptionally high; expect to train people and have them leave 9 month later for a better job elsewhere. Work hours are long and workloads are very large. Unreasonable deadlines and expectations.
I would also add that most of the 5-star ratings you see on this page are likely fake or made under coercion. When I worked there, we were heavily encouraged to leave a positive Glassdoor review, and when people quit we were forbidden to discuss it among our peers or hold going-away gatherings because the turnover rate was so high. Even the hiring and HR managers changed every 12 months.
