The selection process included 4 steps and for me it took relatively short time (around 10 days) : - HR interview (30 mins): my background and experience in the role, motivation for applying for the offered role - Interview with the Head of Data Science (1 hour): description of the role, projects on which the successful candidate will work, company culture and description of working week. - Data Science task (1 day): they sent me a task for which I had a day to prepare the analysis and send it back to them the days after - Onsite interview (1 hour or maybe a bit more) : the data science team and I went through the task and they had some questions and brainstorming about other possible analyses or insights in the results. After that we had the possibility to get to know each other and see whether we were a good fit.
