Initial Conversation with HR, was smooth and HR is very professional. Second 1hr Tech with member on the team: tech depth understand your relevant tech experience, asking basic relevant question. Good interview. Third 1hr Tech with someone who is not on the team but been with the company for years. very scripted questions, I don't know what the interviewer trying to get from these questions. Tech related more about check if you familiarity or know the term definitions. Have no clip with the third interviewer. all tech interviewers are phd level
