Behavioral Case Technical Coding
The whole process consisted of 5 interviews with different members of the team. 3 of them were discussions about my background, my experience and my motivations (Typical HR questions). 1 was a business case analysis (visit Oliver Wyman website for examples) and 1 technical about Python, SQL and Data Engineering. Most of the interviewers were really cool guys, and this made me feel comfortable.

Case Technical Presentation
Sehr freundliche Gespräche, insgesamt vier Runden. Zwei davon beinhalteten Case-Studies. Leider reicht ein 'Nein' bereits aus, um nicht in die nächste Runde zu kommen, selbst wenn die anderen drei eine positive Rückmeldung gegeben haben. Überraschenderweise hat eine Person auch viele Fragen zum Branchenwissen gestellt, vielleicht weil ich schon Berufserfahrung habe – war aber nicht in der Branche tätig. Daher macht es möglicherweise Sinn, sich vorab nochmal über Trends und aktuelle Themen in der jeweiligen Branche zu informieren.

Case Behavioral
You'll go through 1–2 case interviews with consultants. Each interview has two parts: A quick fit/behavioral check, and then a case interview led by the interviewer. The cases are more about strategy and not super formulaic like MBB cases. They really care about how you think structured, prioritize, and communicate clearly, not just if you memorized frameworks. There's some math involved, but it's more about making judgment calls.

Technical Case Behavioral
It was three rounds. Round 1 was about basic ML resume stuff and case studies related to ML (like how to get features, pre processing, training, testing). Round 2 was a pure case study (I'd suggest looking at IIM case books for each type of case and structure) and sometimes you might get guesstimates. Round 3 was mostly HR oriented.
