Pros
There are some amazing and talented people working there. Projects can be interesting. You can work with high-tech microscopes. Convinient location
Cons
The CEO (Balázs Rózsa) embodies everything that is wrong with the company. He is a narcissistic, egoistic person who tries to micromanage everything and be smarter than everyone. This makes working and progressing with you projects unnecessarily difficult. His "revolutions" and "breakthroughs" that he likes to talk a lot (and I mean A LOT) are usually empty thoughts that are based on far-fetched, wannabe ideas and single observations. His work is absolutely unscientific and solely about how to shape data the scientists acquired and not confirming his heuristics into something that "does". And it's the scientists fault if it's not possible. 40+ hours of work is required in shifts, even on the weekend. Naturally, salary doesn't reflect these requirements. Criticism is not accepted as the CEO knows everything better. Public humiliation from him is regular. Most of the time he puts everyone on emails, even if he replies to a private mail. I don't recommend doing a PhD here because Balázs Rózsa insists on publishing only to high impact journals. Since the quality of work is not enough for that (and not because of the people working there), this means that they never publish.
