Your question is Predict Next Hotel View. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Take-home: predict which hotel will one user look at next. Data: user profile (location + gender only), hotel info (rating only), and each user's ordered sequence of hotel views.
Asked in the take-home stage. Candidate found the data too sparse for standard ML predictors and later thought rule-based classification might have helped. Explain how you would formulate the task, build a baseline, avoid leakage, evaluate it, and decide whether more data collection is necessary.
