I have been working for almost a year at N26 and unfortunately, little improvements have been done. There are little to no career opportunities unless you are part of the "circle". They do not invest in their employees, people are most of the time leaving after a year. The salaries are not even close to the market average.
The problem starts with the hiring, they seem to hire buddies, instead of people that get the job done. I do not recommend anyone to work here if they are looking for a serious career job. It is a good temporary job that's it, don't get fooled by the nice flyers.
