First Performance Global interview questions

I got an email asking to interview for the position, and my availability was asked for. I sent my availability to interview, and an interview was set up for a day not within my availability that I had sent. The interviewer apologized and rescheduled the interview for a day that I was available. I shower up 30 minutes early to the interview and sat for an hour waiting on the interviewer to show up. He never showed up, so I sent an email to follow up. This is now a week later and I’ve still never heard from him. I’ve been completely ghosted after trying to schedule a simple interview. I would not want to work for a company like this that doesn’t even follow up to a simple email. If the position has been filled already, an email back saying that would have been fine. Waste of my time and energy trying to apply and interview for this job.
