The first one is the HR interview. Go through their values, projects and details on the website. A few technical questions could be asked about SQL, statistics or ML like what is a With statement. The next one was technical interview which was mostly focused on A/B testing. It checks your knowledge in depth about factors such as power, significance and MDE. What effect does changing any of these values would have on the other. Lots of questions so you have to prepare well for this one. The next one was Coding, which was mostly on data analysis using Python and some SQL queries. There was one question about initializing a class with a list, so OOP also could be asked. The last one was culture fit, behavioral and situation based questions.
