StitchFix Data Scientist interview

Hi everyone! I applied for a Data Scientist role at StitchFix and got a callback for an interview. Was wondering if anyone here went through the process, and if so some pointers etc. for the interview? I heard that they are focused a lot on statistics(hypothesis testing, experiment design etc.), but I'm not strong with those(my focus is more on machine learning and computer science). Any good resources for understanding these topics well enough for interviews?
