Colloquio
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.

One question involved expected wait times for a train that runs every 10 minutes, compared with walking. The train took 5 minutes and walking took 10 minutes. The interviewer kept adding new factors and asked whether the expected wait time or overall travel time would increase or decrease, and why. It was very interactive.

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.

A train arrives at the station every 20 minutes. If you take 5 minutes to run and 10 minutes to walk, what is the expected wait time at the station?
