MediaMath Senior Accountant interview questions

I had an initial phone interview scheduled with someone from the recruiting team. They ended up completely ghosting me and did not call at all. I waited for about half an hour before sending a follow-up if we would be having a call that day. No response unfortunately. It is really unprofessional to totally just leave candidates in the dark like this. It is unacceptable. People take time out of their day to have interviews. The least they can do is send an honest email even if they're saying that they're no longer hiring for this position.
