Ventajas
Good ethical work culture with a clear commitment and actions to support a healthy work life balance. Egotistic managers or any subordinate "abuse" is not tolerated at all. Huge network of experts across different technological domains to learn from.
Desventajas
Despite truly believing they are better than the competition, workload remains high and the toxic "extra mile" culture is still very much there and pushed to get everyone working just a little bit more to compete with peers in order to secure a promotion. There is little to no room for creativity on client projects. Company is mostly run by white German men and is far behind in terms of gender and diversity. I have experienced multiple subtle racist comments, esp. with regards to colleagues working from India. You will be promised the world during the hiring process so make sure to understand which team you are joining and which projects/type of work will you be doing!
