Impossible hours. You will be expected to come in from 10 am to 10 pm while working in Berlin, Saturdays included. This does not get better for remote employees; time zones are not respected. Calls and emails at all hours, and you ARE expected to respond. Little to no time off.
Day-consuming meetings that will go nowhere.
Inconsistent focus on target audience, ideas, and... pretty much everything. Scatter-shot techniques without proper time for anyone to prepare.
Constant responsibility whiplash. Because so many people quit, jobs are handed off without much training or, once more, preparation. CEO expects you to just get it anyway.
