A technical screen for a Data Scientist role at Google that went deep fast. The whole thing was basically one extended ML design problem about URL classification, and they kept pushing on evaluation methodology and deployment strategy in ways I wasn't fully prepared for.
“I jumped straight into feature ideas (URL length, domain age, TLD type, presence of subdomains, etc.) and got through the modeling part okay.” The rest of the author's notes on Data Scientist interview at Google, Technical Phone Screen round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
