Many rounds but the responses are very fast. One initial phone interview, one quick data assessment, one quick work review, one presentation, and the final call. It's a lengthy process, but it demonstrates what the job entails.

first round is a phone screen that starts with basic questions, such as whether you need sponsorship and your GPA, followed by questions about your familiarity with the company’s goal and products and some general behavioral questions; second round is a 45-minute online assessment with two parts that tests your attention to detail; third round is a 1-hour interview that focuses on discussing materials they will send you in advance. HR is very responsive and typically schedules one interview per week, and since there're suppose to be another two rounds (one is a presentation and another is talk with an exec person?), the entire process might takes about a month
