Got a code challenge and did a live coding interview virtually. No output needed just taking logic. It was a really tough leetcode problem but you are able to understand what the interviewer is asking. The interviewer was nice and helpful

There was no direct contact with anyone from Dropbox. I was sent a technical assessment that seemed to be of normal difficulty level and was moved on to the second round which was an extreme jump in level from the first. I asked two other engineers that have been coding for 3 years and they both didn't think they'd be able to finish the ask in the given amount of time.
