The technical interview process felt poorly calibrated and inconsistently framed. The main issue was not that the questions were difficult, but that several rounds seemed to test a different skill set than what was communicated beforehand.
In practice, it often felt unclear what the primary evaluation criteria actually were. Some rounds started as if they were focused coding exercises, but the expected discussion appeared to extend into broader design, scaling, or product-style considerations without that scope being made explicit early on. That made it difficult to judge how much time to spend on core implementation versus higher-level tradeoff discussion. The result was a process that felt noisy rather than rigorous.
