I wasnt too prepared for the interview. I was asked questions on XGBoost, Logistic regression, some stat concepts, some drilling into NLP algorithms. Finally, there was a some drilling into web-visualization type questions using SVG etc. Overall, the questions werent super hard but I felt underprepared.
