BrightWire interview questions

I applied through glassdoor I remember, and had a zoom interview for 30 mins. I did not expect, but the person who showed up in the first round was the CEO of Brightwire so I was surprised. I don't think I did too bad and he said he will get back to me within a few weeks but he ghosted uptil now. It's been over a month. I assume he was using a speaker phone and that made my speaking to howl back to my ears so I was VERY distracted and couldn't hear what I was saying. Bascially speaking like into vacuum chamber except that it's not the vacuum eating up my voice but the howling. I told him the audio system isn't working well but he didn't take any action. I also emailed the HR because I saw another opening that seemed like my fit but they didn't answer that either. I don't think they have an actual HR department because I did not see any professionalism in HR process and seeing CEO in the first interview is pretty unusual.
