Twitter Data Scientist Interview

Hi everyone, I have my Technical 1 hour Data Scientist Interview at Twitter coming up. 1. I wanted to know what to expect for the statistics questions? How difficult are they? I know there will be a metric based case study which I'll be able to prepare for, but I'm not sure how involved the statistics questions will be exactly. More ML based or pure stats? 2. They also want me to code during this interview, what kind of coding questions are expected for a DS role? Are they similar to a SWE role like Easy/Medium Leetcode? I've already gone through the initial 30 min resume based interview. TIA #data #datascience #twitter #datascientist #interview
