Initial phone interview was fine, lasted around 20 mins. In person panel interview came next. Met with 6-7 people, also went well. They were prepared with a number of good questions. I was called back for an interview with the director and that's when things took a turn. He arrived around a half hour late and seemed very rushed. I don't recall the questions being particularly difficult but he reiterated several times that this was a "very hard job". Seemed he was kinda trying to talk me out of it which I thought was strange. Interview ended positively and unprompted he said I would be hearing from HR. I never heard from Tesla again.
