First contact recruiter was very knowledgeable about position and company. Very unusual, turns out she was one of the founding employees. Hiring manager asked early seemingly innocent questions which later on served as disqualification ('thank you for your honesty') . Barrage of online tests passed, then an homework assignment for second round. Technical interviewer at second round did not ask about assignment and seemed rushed. Case study question, explaining technical material, guy knew what he was doing. Almost immediate rejection email after second round
