I ask the equivalent DS question in a lot of my interviews. Generally people tell me about the hot new XGBoost model they fitted, and I ask them how much better it was than logistic regression. 9/10 they don't have a good answer. That being said, my favourite answer was from a candidate who told me that Kaggle contestants didn't use log reg, and therefore it was a bad choice. Oddly enough, we didn't hire that candidate. OTOH, I've worked at places where they wouldn't hire you if you didn't talk about your awesome neural networks/XGboost experience, so it really depends on the interviewer.
