2 round online interviews. first round is leetcode, 2nd round is online 1to1 zoom interview, asked me brain teaser questions only, did not discuss cv. i f up on quite easy questions. shame on me.

Applied through a referral. The first step was an initial HackerRank-style assessment that was pretty straightforward and mostly Excel/data-analysis type work. I had to look up values, calculate metrics like profit, and answer practical business/math questions. The second round was with a TDOE and was much more intense. It focused on live problem solving, analytical reasoning, and probability/math concepts. I would recommend being comfortable with expected value, expected wait times, conditional probability, basic optimization, and explaining tradeoffs clearly. The interviewer cared a lot about how I broke down the problem, not just the final answer.

Only did the mathematical problem solving interview. No advanced technical knowledge required. Focused mainly on creativity within arithmetic and statistics questions. Focus more on showing your thought process than just solving the question since the interviewer is happy to help if needed.
