Applied online and received interview invitation through email. In-person interviewed with HR and operation manager at Delta office, it went well, good vibe during the interview. In two weeks, was told to schedule a 2nd-round virtual interview with CEO, but HR suddenly changed the mind and rushingly scheduled a face-to-face interview without consulting the time and availability with candidate. Never hear back after the 2nd round. Lack of feedback and follow up, unprofessional; always read but not respond the follow-up message, disrespectful; drag the hiring process, inefficient.
