Difficult Positive United States

The path I went through felt very math-first, then coding/verification second. After a recruiter touchpoint, I ended up with technical rounds where probability and strategy questions came up early, and the sessions were intense enough that it didn’t feel like I could “wing it.”

One round focused on building and validating an optimal strategy in a game with dice. I first developed the strategy and then had to live through a code-based validation step to check that the approach was consistent. Another technical session went even more directly into strategy: I was asked to derive an optimal Baccarat strategy, walking through the steps end to end. That part took about an hour and, honestly, one of the questions felt like it crossed into a LeetCode-hard style of challenge.
