The process took 2 weeks.

The experience was similar to what has already been described by others. I passed the first two stages but did not pass the system design interview. My first attempt was definitely on me — I was not prepared well enough. I took the feedback seriously, prepared much better for the second attempt, and expected a more balanced evaluation.

However, the second system design interview felt frustrating because the interviewer repeatedly guided the discussion toward minor or less important parts of the design, which consumed a significant amount of time and prevented me from properly covering the core architecture and trade-offs. Overall, the process was useful, but the system design stage felt inconsistent and highly dependent on the interviewer’s style.
