I went through a few rounds of interviews. All rounds felt friendly and professional besides the last one. The 4 other employees I talked to had given a thumbs up to my candidacy and seemed like real high-achievers. The last interviewer was overly selective despite this (did not want to learn about my experience, qualifications, or traits). The interviewer stopped asking questions 10-min into a 30-min interview. This 1st-hand experience confirms what I've heard through the grapevine: despite (or maybe because of) their killer technology and potential TAM, some employees are cocky. I feel like I've dodged a bullet after this interview.
