Technical Coding Behavioral
It began with a technical assessment on CodeSignal that felt a bit off, with camera, microphone, and screen sharing monitoring, plus ID and selfie uploads. It seemed like a lot of effort for a high-pressure situation, but maybe their standards are flexible and they just want to see if you can code, likely with automated scoring. Then, a recruiter call, followed by a virtual on-site with three interviews. I didn't get the job, but the recruiter gave feedback that the engineers were overly critical and wanted a very specific approach. Despite positive signs during the interviews, their perception of my performance was totally different. Casual chats with the engineers felt really bad, like they had zero interest, possibly because they didn't enjoy running the interviews. This felt like a warning sign, and honestly, Dropbox's appeal has really declined.

Coding Coding
The hiring process involved an online assessment, followed by a recruiter call, and then two technical interviews. Overall, it was a pretty good experience, but the answers for the interviews were judged against an internal answer sheet. Neither the first nor the second technical interview allowed for much critical thinking or imagination; it was more about whether you arrived at the desired solution. It felt like it required 'leetcode brainrot'. They are quick to reject, and providing feedback upon rejection makes it a professional experience, though I'm not entirely satisfied with the question choices and how the grading was done.

Technical Coding System Design Behavioral
I had a really good time interviewing with Dropbox. They have a solid process that included a phone screen, two coding interviews, a design systems interview, and then a final chat with HR. All through the process, the HR folks and the interviewers were super supportive and made me feel comfortable, which helped a lot with the usual interview jitters. They seemed interested in both what I could do technically and if I'd fit in, making it feel more like a conversation where I could learn stuff rather than just being tested. It really showed me that Dropbox cares about making the interview process good for candidates and made me feel respected, so the whole thing felt fair and human.
