Behavioral: Complex Technical Problem You Solved (Data Scientist – Onsite)
Prompt
Describe a complex technical problem you personally resolved. Include the context, alternative approaches you considered, the trade-offs involved, and the final outcome.
What to Cover (use a STAR-style structure)
- Situation: Briefly set the context (team, product, scale, constraints).
- Task: Your explicit goal and success criteria.
- Alternatives: 2–3 viable approaches you evaluated and why.
- Trade-offs: Latency vs. accuracy, interpretability vs. complexity, cost vs. performance, etc.
- Actions: Your contributions (analysis, modeling, experimentation, collaboration).
- Results: Quantified impact (metrics, speed, cost), and how you validated it (A/B test, guardrails).
- Learnings: What you’d do differently or generalize.
