SIXT Data Scientist Interview Guide: Common Questions & Rounds
Introduction
The SIXT data scientist interview process runs 4 to 5 rounds, including an HR screen, a take-home technical assignment with up to 7 days to complete, one or two technical interviews, and a culture or manager interview. Timelines typically span 2 to 8 weeks from first contact to decision.
The process screens for applied modeling ability in regression, classification, and forecasting applied to fleet and pricing operations, with candidates expected to translate operational business problems into working solutions rather than demonstrate theoretical depth alone. The take-home assignment specifies the algorithm to use, narrowing evaluation to the quality of analysis and interpretation rather than model selection.
Interview Topics
The SIXT Data Scientist Interview Process
Recruiter Screen
The process opens with a 30-minute HR screen covering career history, motivation for switching roles, and salary expectations. The recruiter explains the role broadly without going into technical depth. One candidate described it as “very normal,” with the interviewer providing general information about the position rather than probing specific skills.

Take-Home Assignment
Candidates receive a structured assignment with up to 7 days to submit it. The brief is specific, including prescribed visualizations and a designated modeling algorithm, so the evaluation focuses on analytical execution and interpretation rather than model selection. One candidate noted: “In the modelling part, they tell you the algorithm to use, which I think is a good starting point to guide your analysis.”

Technical Interview
After the take-home is reviewed internally, candidates who advance move to a technical interview that probes the theory behind the algorithm specified in the assignment. Candidates should be aware that the interviewer conducting this round may not have seen the submission itself, only reviewer notes, so the discussion centers on the method’s application in the assignment’s domain rather than a walkthrough of the submitted work.

Second Technical Interview
A second technical round follows, covering modeling and data science concepts relevant to SIXT’s operations, including pricing and fleet-related case scenarios. Candidates report this round involves applied problem-solving questions connected to mobility and car rental business problems rather than abstract algorithmic puzzles.

Culture and Manager Interview
The final stage is a culture or hiring manager interview, typically 30 to 60 minutes. The conversation focuses on alignment between the candidate’s goals and the role’s scope, working style, and experience in relevant domains such as mobility or analytics. For senior roles, this stage may include additional rounds with a regional or global head of data.
