1) Choose between phone call or writing answer of a questionnary. 2) Technical assignement to be done in 4 days containing a data science case with anonymized real word data. In my case the test consisted in forecasting financial flows of N26 users. The test is very fun to do and I think that it gives you a good overviews of the task you might be doing if you join the team. 3) Skype interview to review the technical test with team members. This part is more of a discussion than a interview, yet they will use it to evaluate your ability to express technical concept in a understandable way,. Furthermore we done an review of the technical assignement. Members of the data science team were extremely nice and I actually had a very good time during the interview. 4) last interview with lead data and lead data science. This interview is the last round the gozl is for you to meet the leads of the team so that they get to know you and you get to know them. The Interview once again was very enjoyable, everything is done to make you chill and it really gives you to join the team. At the end of the process I received an offer that fits my expectation, they even raise my salary compared to the initial indication. The interview process convinced me about my will to work at N26 and that the atmosphere + the data N26 own represents a dream combination for any data scientist. Unfortunately my personnal situation couldn't allow me to work in Berlin. It is such a shame that there exist no reliable transportation mode between Berlin and Bruxelles: either expensive and polluting by plane or very long (6h) by train.

- first screening interview - got an intense challenge with 5 days time, time-series financial account data from 6 month and build a model to predict the 7th month - did not complete the challenge to their approval
