Brief introduction followed by case interview using code to solve the problem. The interview is very challenging because it involves solving a case interview using an imaginery data set and "verbally coding" to the interviewer. Interviewer was friendly and helpful when I got stuck midway. The case interview was split into 2 parts roughly, first part focused on structuring the problem and coding syntax. The second part required a bit of creativity to solve the case beyond just the code.
At the end, interviewer was willing to provide feedback and areas for improvement.
