First interview was with someone on the team. 2nd interview with another team member, walking through a case. 3rd interview with head of operations. I didn't move past the 2nd interview, that is where I was rejected.

Behavioral rounds are easy. You can bs through your past experiences. The technical case is tough. The data scientist from other team runs you through an AB test case that felt like an actual experiment they ran not some made up scenario. The quality of the case was impressive. You have to go through each metric and explain what it means. He asekd me to really take time and think through the numbers a few times in the intervieview. I couldnt apply the typical consulting framework or case interview process as it sounded like a real business case and data were real. The interviewer was not really a small talk guy which caught me off guard at first. But when I was clearly going in the wrong direction he didnt just move on. He asked something that made me stop and rethink. I didnt appreciate it in the moment honestly. Walked out thinking I bombed it. Was kind of annoyed at myself. But I kept thinking about it and honestly part of me just wanted to work with someone like that. You can tell when someone actually knows what they are doing. He also mentioned the company works bottom up and encourages using claude code which made me want to join the team even more. Study the prep package they send you. Brush up on pvalues and statistical significance. Dont try to fake your way through the numbers
