I applied online. The process took 4 weeks. I interviewed at Glassdoor (New York, NY) in Mar 2018
Interview
One kaggle-style data challenge (an imbalanced binary classification problem), followed by 2 phone interviews. The take-home data challenge tests your application skills. If you have a good ranking, you get to the next two rounds -- phone interviews. However, it is very selective because there are many candidates.
Interview questions [1]
Question 1
Many questions about Machine Learning Basics, including regularization, derivations of bias variance, and a small algorithm question.
