Dropbox Senior Software Engineer interview questions

Started with technical assessment via code signal which was kind of uncomfortable. Monitoring by camera/microphone/screen share, ID upload, selfie, etc. A lot of work to keep someone in a high pressure environment but I think standards are "loose" here. They just want to know you can code and it's probably all automated. This was followed by recruiter intro, then virtual on-site of 3 interviews. Got rejected and recruiter was happy enough to provide feedback. Feedback reflected engineers that were very nit-picky and were looking for a specific solution. Positive signals during the interview, but completely different story in how they perceived my performance. My casual conversations/questions with engineers felt like nails on a chalkboard. No interest. Perhaps because they're not excited to run these interviews. This felt like a red flag and the reality is that Dropbox has fallen off a cliff in terms of external appeal.
