Method defense in data science case studies: the 'why this model?' question

Data science case study interviews evaluate method judgment, not just coding speed. The canonical failure is a candidate who produces correct code but cannot explain why they chose a specific model or statistical approach over alternatives. Interviewers probe this directly: 'Why did you use a random forest instead of logistic regression here?' 'What assumptions does this model make, and how did you verify them?' 'What would happen to your estimate if this assumption was violated?' These questions are designed to separate data scientists who understand their methods from those who apply familiar tools by default. AI is useful for case study preparation in the rehearsal phase: given a case prompt, it can generate method-choice rationales with explicit tradeoffs, suggest the one or two alternative approaches the candidate should have considered and discarded (and why), and format a caveats summary that shows intellectual honesty about the method's limitations. The rehearsal value is that method defense is a skill that improves dramatically with practice — the first time you articulate why you chose a method, it sounds uncertain; after ten rehearsals, it sounds fluent and grounded. AI also helps with the meta-skill of volunteering tradeoffs proactively: in strong case study performances, the candidate raises the limitations before the interviewer asks, which signals confidence and statistical maturity.
