Resume Killers (Avoid!)
Listing 'Python, TensorFlow, SQL' as skills without showing what you BUILT with them (projects > tools)
Describing analysis without business impact — always connect to revenue, retention, or efficiency gains
Using metrics without context ('accuracy 95%' is meaningless without baseline, class distribution, and business implications)
Not including links to Kaggle profiles, GitHub repos, or published notebooks
Omitting A/B testing and experimentation experience — this is table stakes for top DS roles

Top Interview Questions
Be prepared for these common questions in US tech interviews.
Q: Explain the bias-variance tradeoff with a real example.
MediumExpert Answer:
Bias = model too simple (underfitting). Variance = model too complex (overfitting). Example: predicting house prices — a linear model has high bias (misses non-linear patterns), a 100-depth tree has high variance (memorizes training data). Solution: Random Forest or XGBoost with regularization balances both.
Q: How would you design an A/B test for a new recommendation algorithm?
HardExpert Answer:
Define metric (CTR, revenue per user). Calculate sample size for 80% power at 5% significance. Random assignment to control/treatment. Run for 2+ weeks to capture weekly patterns. Check for novelty effect. Segment analysis by user cohort. Guard against peeking with sequential testing.
Q: A model has 95% accuracy but stakeholders don't trust it. What do you do?
HardExpert Answer:
Accuracy might be misleading (e.g., 95% of data is one class). Check precision/recall/F1. Use SHAP values for model interpretability. Build a confusion matrix dashboard. Show stakeholders specific predictions with explanations. Start with human-in-the-loop deployment.
Q: Walk me through a project where your analysis drove a business decision.
MediumExpert Answer:
Use STAR: analyzed customer churn patterns, discovered users who didn't complete onboarding within 48 hours had 3x churn rate. Built a predictive model (AUC 0.87) to flag at-risk users. Recommended targeted email campaign — reduced 30-day churn by 15%, saving $500K ARR.
