Pros
Zalando is still a young, agile and challenging environment with a lot of opportunities in all areas. It gives most people the opportunity to learn and practice things in a multi-million Euro environment. The amount of responsibility people get is over-proportional compared to other companies. The salaries in most areas like Product, Engineering, Legal and HR is competitive.
Cons
Zalando has invested much in improving their organization and the people development recently. And still, the culture which is set by SVP and VP's do not reflect these great ideas. Especially the SVP's do not invest in their own personal development ("as they are there forever, created this company - so why bother?"). People who do not live the Zalando culture still gets promoted. This creates a culture break between executives and the teams. The strategy gets a reset every year, at least this is how it feels for the people - the Zalando Platform seems to be dead as there is literally no investment in it. A real vision is missing where Zalando will be in 2-5 years (revenue targets are wish-thinking and are no vision which people will buy).
