The interviewer was very informative. The questions appeared basic initially, but they required deeper reasoning, strong fundamental knowledge, and careful problem-solving instead of simple, straightforward answers throughout the interview process.
The process was structured and intellectually challenging. It typically involves an initial recruiter screen, followed by probability, mental math, expected value, and game-style problem-solving interviews. Interviewers focus more on reasoning, communication, and adapting to feedback than memorized answers.
