Airbnb·Machine Learning Engineer·Onsite - System Design / Architecture
- Design a machine learning system to classify Airbnb listings as family-friendly so users can filter by that attribute.
- What happens if hosts deliberately mislabel their listings to show up in the family-friendly filter?
- How would you make sure the classifier doesn't unfairly filter out listings from certain hosts or neighborhoods?
- How do you handle cold start for new listings that have no reviews or booking history?
“I framed it as binary classification pretty quickly, which felt right, but I spent too long on label construction before touching features.”
