Technical Questions

• • Design an A/B testing framework for an e-commerce platform. How would you determine sample size, handle multiple testing, and ensure statistical rigor?
• • You're building a churn prediction model for a subscription business. Walk me through your approach: feature engineering, model selection, evaluation metrics, and how you'd deploy it.
• • How would you approach analyzing causality vs. correlation in observational data? What techniques would you use to establish causal relationships?
• • Explain how you'd build a recommendation system for a marketplace with cold start problems. What algorithms would you consider?
• • You have a dataset with significant class imbalance (1:100 ratio). How would you approach modeling this? What metrics would you optimize for?
• • Walk me through your experience with time series forecasting. What methods have you used (ARIMA, Prophet, LSTM) and when would you choose each?
• • How do you communicate complex statistical findings to non-technical stakeholders? Can you give a specific example?

Cultural Fit Questions

• • Tell me about a data science project where your initial hypothesis was wrong. How did you pivot and what did you learn?
• • Describe a situation where you had to balance statistical rigor with business timelines. How did you make tradeoffs?
• • How do you approach stakeholder management when your analysis reveals inconvenient truths about the business?
• • When you discover a data quality issue in production, what's your process for investigating and fixing it?

Current Trends

• Data science roles grew 64% year-over-year in LATAM as companies move from descriptive analytics to predictive modeling. Demand for causal inference and experimentation expertise increased 89%.
• ML skills are now baseline: 87% of data scientist postings require production ML experience, up from 54% in 2023. Pure BI/analytics roles are declining.
• Domain expertise commands significant premiums: data scientists with vertical knowledge (fintech, healthcare, e-commerce) earn 25-35% more than generalists.

Demand Factors

• U.S. shortage of data scientists with business acumen: 38,000+ open positions vs. 16,000 candidates with 3+ years of stakeholder-facing experience.
• LATAM data scientists bring bilingual communication advantage: 82% have B2+ English proficiency, critical for explaining complex findings to executive teams.
• Real-world experience at scale: LATAM data scientists have built models for companies processing billions in transactions, demonstrating capabilities matching top U.S. tech companies.
