Flipkart's data-scientist interviews test end-to-end ML system thinking, the offline-online gap, and experiment design at e-commerce scale.
In 2026 expect applied ML design (predicting delivery delays at order time, including features, model choice, retraining cadence, and feedback loops), diagnosis questions (a pricing model that looks good offline but underperforms live), and experiment-design questions where network effects break naive A/B tests. Interviewers reward candidates who reason about distribution shift, train-serve skew, feedback loops, and interference rather than just naming algorithms. Flipkart's data science powers pricing, delivery, and ranking, so grounding answers in a real e-commerce workflow with a working feedback loop stands out. Prepare ML system design, evaluation pitfalls, and experimentation.
