Very bad. Asked for reference middle of the process. which made me think I am getting the job. a long presentation, and picking on unrelated details that was not relevant to the presentation. No regards for the interviewee time, asking to meet the day later, or have the presentation ready for Monday when provided Friday. So it was clear they have no respect for your time. After going all the way and asking for references, they said oh we didn't even call them, we just need to ask them, and we have no intention to hire you. which was very unprofessional to me.
