Pros: Depends on which group, I was in a very good one, with very professional and skillful people, learned a lot, and part of the time had the opportunity to implement interesting things. Had a good amount of (paid) days off.

Cons: It can be so dynamic, and the whole group might change to the worse (might happen anywhere, but this is a highly dynamic place in comparison to others). Bad conditions in comparison to other global companies (including salary, gifts, etc.). The company as a whole prefers to hire continually a great amount of entry level engineers and doesn't care much about retaining the good experienced ones.

Pros: Stress-less environment, flexible hours and good atmosphere.

Cons: The main issue is non-sexy compensation, so most SW developers leave the company after a short period.

Pros: It is a good place for junior developers to gain experience.

Cons: Compensations are below average. The meals are quite bad.
