The interview process up until the final round was fairly standard and everyone I met was pleasant. I had a recruiter screen and then did the technical phone screen with another engineer (LC medium). I passed this and moved on to the final round. My final round lasted over 5 hours (including breaks) and was a gauntlet. Nerves really got to me and I didn't do as well as I'd hoped. Beyond that, several interviewers seemed very uninterested or, unfortunately, even borderline hostile. One interviewer got up to receive a package in the middle of the interview and left me to work in the IDE alone. Only one of my five interviewers that day actually seemed interested in having a normal conversation and evaluating me beyond my technical skillset but also as a potential colleague. A friend who interviewed here also mentioned during his final round, his non-optimal solution was laughed at because it didn't pass test cases. Perhaps we both got difficult interview panels, but the process was not very welcoming. Afterward, I was sent a pretty standard rejection email and was informed they would not be providing any kind of feedback.
