The first round phone interview consisted of strictly behaviorals and took around 15 minutes. The superday consisted of 3 back to back 30-minute interviews where I was asked a mix of mathematics, statistics, computer science, economics, and brainteaser questions.

2 final round interviews, and then offer in the next week. 2 panels of 2 interviewers each. Pretty easy and chill. Prepare technicals, coding, math, stats and know your behavorials.
