Pros
They used to offer some sport activities
Cons
Oceans of legacy code, and toxic atmosphere due to lack of growth opportunities. Legacy, legacy and LEEEEGAAAACYYYYY. In the three teams where I have worked so far, 90% of the job we do is dealing with legacy code and maintaining old application with a huge operational overhead. There are very few new projects, and nowadays those are done by external developers. Zalando rents engineers from Thoughtworks, gives the new projects to this developers with a very tight time deadline (so not good quality job is done), and then these guys leave. Then the internal employees maintain these applications. When the evaluation comes, they tell you that your work wasn't "impactful", and when afterwards you ask to work on new projects that are more impactful, you get the same old maintenance of legacy "because it needs to be done". So many people focus on competing to show off whatever they do, always thinking about the next evaluation.
