Initial phone screening and 2nd round tech interview were pretty easy and pleasant. Final round consisted of 4 1-hour slots with various team members. First 2 interviews were just OK, the last two were just terrible - 1 interviewer was extremely disinterested and didn't really explain the task I was supposed to be doing- The last interviewer just talked way too much and interrupted a ton, he seemed to have forgotten that I'm the one being interviewed and not him. He also went 45 minutes over the scheduled timeslot. Exhausting. Got ghosted after the final round. My recruiter also ignored a follow-up email from me (despite being specifically told to write an e-mail if I don't hear back after 2 days).
