Through an engineering consulting company, I had an online interview with the main software engineer, and two leaders from backend and frontend. There were also two people from the engineering consulting company

One of the slowest processes I’ve ever been part of. Two technical interviews covering topics ranging from detailed C++ compiler implementation questions to various (mostly theoretical) networking questions. At the end of the final interview, I was explicitly told I would receive feedback — whether positive or negative — within a week at most. A month later, I still hadn’t received any feedback, despite having followed up with the technical team who interviewed me. Eventually, I contacted HR, who informed me that I hadn’t passed the interview — but unfortunately, I still never received the promised feedback.
