Went through two rounds of interview with the hiring manager and HR. First round of interview went very well. Hiring Manager is very kind and respectful. Spent two hours talking about my past experiences and key achievement. Hiring Manager shared the background of the company and business. Discussed her goal and what to achieve. Second round interviewed with HR right after the interview with the hiring manager. HR was late, during the interview session seem like doing other stuffs and no face expression. Conclude the interview within 30min and without any further elaboration. Mentioned the outcome will be conclude within 2 days but no revert/ response afterward. Personally think that even no being selected, at least revert with the outcome and show some respect.
