Remco, Inc. Purchasing interview questions

2021 interviewed via phone. Was instructed to come on site only to be told the hiring manager was not there that day to interview me. The interview had been set up 1-2 weeks in advance. I completed a paper application only to be questioned about a different job that I never applied for nor was I interested. It’s like 1 hand doesn’t know what the other is doing. I waited never even got a rejection letter. I still don’t know if such a job ever existed. ??
