Extremely unprofessional. Interviewer changed the interview time and date 30 minutes before the original meeting time on Teams. (Without other notice or explanation) While I have took day off in order to attend the meeting. I sent an email to the interviewer to ask about the arrangements and got no response. This company wastes candidates time with no respect. Finally i met the team supervisor at new schedule date. However, he did not apologize / mention about the changing schedule. The interview was quick and the interviewer showed indifferent
