NK Communications interview questions

Unprofessional interview process. Applied, gave a window of time slots as requested, at no stage was a time confirmed, got a message asking was I attending the interview, I informed him I had not received a link, he accepted this was his error and we agreed a second slot. I again requested a zoom link twice, heard nothing back. Once interview slot had passed I received a reply which implied the issue receiving the link was on my side and that they would be proceeding with other candidates. Extremely unprofessional and honestly disrespectful of my time. Have never had an experience like this but evident I dodged a bullet.
