datascience.interview on Instagram: "This is a real ML question I recently asked for a senior data science position. A model with 99% accuracy can still completely fail in production. This happens often with imbalanced datasets like: • Credit card fraud • Churn prediction • Disease detection That’s why in interviews, accuracy alone is not enough. Interviewers expect you to reason about the right metric — not just quote accuracy. Save this — you will be asked this. #datascientist #datascience #ma
