I recently went through a multi-stage interview process, which I found to be overall a good experience. My interview lasted for an hour, during which they asked a wide range of detailed and in-depth questions. After the interview, I followed up twice to inquire about the result. The first time, my message was read but not responded to. Hence, I sent a follow-up message, and they eventually replied, apologizing for having overlooked my earlier message. Unfortunately, I did not receive an offer in the end.
