I never thought I'd leave a positive review about an interview process where I didn't end up with the job, but here we are. From the first message, this experience was different. The interest shown, the attentive communication, the speed of the process itself, and the overall friendliness of everyone I spoke to (in 6 rounds!) is not something I've ever encountered. It was a great experience and while disappointing to not receive an offer, I enjoyed every moment of the experience (except the rejection I suppose). Keep doing what you're doing in the interview process. As I mentioned during the process, other hiring teams should be taking notes from you.
