I applied online. The process took 3 months. I interviewed at Boston Consulting Group (Berlin) in Jun 2025
Interview
A lot of interviews. HR screening + Online Assesment + 3 Technical Interviews + 1 Buisness case. Classical ML knowledge is sufficient but one really needs to convey messages confidently and strongly. It is more about your presence than the actual answers sometimes.

One Case was to predict the effect of discounts on drinks in a supermarket. What should you predict and what tools would you use to do it.

Coding challenge, then soft skills which i did not get to. Coding challenge was online timed in a third party tool. Not very hard but needed more time and didnt move quick enough.
The process includes six stages: HR screening, CodeSignal online assessment, basic pandas and data science case interview, followed by three business case interviews focused on practical problem-solving and business impact.
