You can easily be accused of serious matters without providing proof or explanation, hence no opportunity to defend yourself (which in fairness might be difficult when you are unaware of the issue that you are being accused of) Guilty until proven innocent is the principle at N26. No HR involvement. Slander and defamation is enough to make you lose your job.
Extremely unprofessional atmosphere. Loads of young inexperienced people with 0 background in finance or banking trying to run the company as a social club.
Personal lifestyle of many of the employees taking a toll on the professional relationships and dynamics. I understand it is Berlin but there should be clear borders.
Unhealthy atmosphere at a professional and hygienic level.
