Pros
Some of people are nice and technically good - you can try to learn from them, if you and they will have time. The 10bis meals are nice to have, but a lot of much smaller companies have it as a standard already. Summer "nannies" for workers' children. Small bonuses there and here, as the most of IT companies have. Company support (at least, it seems so) for different interests / hobbies sections.
Cons
Salaries are comparatively low (even with RSUs) and not worth all the minuses, described below. The more you work there, the less possibilities you have to advance in a career or money. Sweat factory. More "results" & reports, even stupid and abstract - is the key to success. All the given bonuses seem to be a tribute to tradition, then some kind of prize for achievements. Sometimes good luck or good speech knowledge can give you much higher salary, than for a guy who knows more / works harder as twice as you. HR is completely "robotic" and works on basis of standards from like 70-80s of the previous century; they have absolutely no influence on inner personnel processes, needs etc (ok, except of very small things). The more responsibility you try to take, the more resistance you'll have. Easy going to enforce you to work additional hours on a global salary, even if it violates the labour laws. Incompetent people are hardly fired. No company "atmosphere".
