The technical screening comes after the initial phone screen. This interview will involve coding, statistics, and machine learning. You can expect, at least, two coding questions, one involving SQL and the other an algorithm coding type question. The coding portion is done over a shared code editor. Remember to take the time to go over your thought process with the interviewer. There is also a section on “approach”, detailing how you got to the solution and why you use the steps you used.
