Magna Technology Group interview questions

Applied through Linkedin and had an internal recruiter reach out to set up a virtual screening for 15 minutes. Half way through the call the recruiter said he was impressed and wanted to move me to the next round to do a virtual interview with a sales director the following day. I show up for the interview and no one joined the call. I emailed the recruiter and sent a follow up, but no response. At least have the decency to reach out and let me know what happened rather than waste my time. The recruiter also mentioned to ignore his reviews that might be posted out there which came off as very unprofessional.
