Pros
Great products. The Brainlab restaurant serves awesome meals. At SnkeOS (Brainlab's spinoff), where I was employed, the offices are well equipped and really cozy. Less so at Brainlab HQ. The majority of colleagues are friendly and professional, and the company has multinational experts from diverse backgrounds. Brainlab HQ offers a private gym, SnkeOS employees get access to Gold's Gym (memberships are paid by SnkeOS).
Cons
There are very few good team leaders in the company. As a result, turnover is high, and the company quickly loses smart people. Some managers can be extremely confusing, chaotic, and nontransparent. The whole environment is insanely political, and full task delegation is infrequent. There are many micromanagers, control freaks, and mansplainers which creates a toxic atmosphere rather than one based on mutual trust. The CEO cares about products and profits, but much less about his employees who actually make his visions come true. People are heavily underpaid and overtime is not reimbursed, though often demanded. As a matter of fact from SnkeOS: an employee with a Bachelor's degree and 15 years of relevant experience earns the same salary as a freshly graduated PhD with almost no corporate experience. The HR specialists pretend to offer flexible working hours, but the truth is there are mandatory 'core working hours' when everyone must be available, which makes it a 9-to-5 job. There is no company credit card, most team events must be paid by employees individually and are not reimbursed. There is no home office allowance, and absolutely no additional benefits. The company does not offer working from your home country unless you are an EU/EEA citizen (and in this case, you can only work 10 days per year from your home country). Annual pay increase (due to inflation) is absolutely not guaranteed.
