Data Scientist Interview Preparation at Coupang

Key frameworks and strategies for Data Scientist interviews.

Master the STAR Method

Structure answers with Situation, Task, Action, Result. Emphasize the problem you solved (20%), the analytical approach and models used (40%), implementation details (20%), and quantified business impact (20%). Always include metrics and statistical rigor.

Essential DS Frameworks

- **ML Model Selection**: Linear → Tree-based → Ensemble → Deep Learning progression - **Feature Engineering**: Domain knowledge → Transformation → Selection → Validation - **Model Evaluation**: Accuracy vs Precision/Recall vs F1 vs ROC-AUC based on problem - **Experimental Design**: Hypothesis → Sample Size → Test Design → Statistical Significance - **DS Workflow**: Problem Definition → EDA → Feature Engineering → Modeling → Evaluation → Deployment

Interview Process Timeline

**Phone Screen (45-60 min)**: ML fundamentals, statistics, SQL/Python coding basics **Technical Round 1 (60 min)**: ML algorithms deep-dive, model selection and evaluation **Technical Round 2 (60 min)**: Take-home case study or live coding with data analysis **Technical Round 3 (60 min)**: System design for ML, A/B testing, experimentation **Behavioral Round (45 min)**: Cross-functional collaboration, stakeholder communication
