No overtimes, great work/life balance, flat hierarchy, autonomy, good office with free food, fruits and candies. 20% of time dedicated to learning and personal projects.
Desventajas
Can't work from home (Sometimes that would be good). Strict arrival time (not later than 11 a.m.). Maybe there are not so much career options, but you have freedom to increase your technical skills greatly.
Culture and People. That says it all. First company I work for with trust and autonomy so much there, and learning and curiosity being what is expected of everyone, and supported in all ways.
Desventajas
nothing really. it's not all pink and blue all the time, but with the right attitude all problems get solved
