I applied through the website in April and I started the interview process in May. Overall, the interview process was composed of five hangouts, each one of 1-hour time.
The first step was just a background check with a representative of the HR department. Regarding the other steps, the focus was on N26 and related case questions. I was told in advance with whom I would be interviewing and each interview has been stimulating with smart and polite people.
Overall, It has been a pleasure to be a candidate for N26 and I really liked the whole recruitment process and the chance to talk with smart people. Based on my experience, N26 has been the best interview process by far.
