DDN Solutions Engineer interview questions

1 30min phone screen with hiring manager 1 1hr technical interview answering questions about syntax. Interviewer kept asking questions even though I kept telling him that I don't know the answers to these topics, so we should skip them. Interviewer never gave me an answer, so I had to keep asking for answers after I got the questions wrong. It was his first time interview, so I give him some credit for trying. He never made me feel bad for not knowing anything. Supposedly I was to have one more 1hr long interview with other hiring managers to see which team I wanted to me on, but I never heard back. I followed up a week later, and still nothing. It's been 2 weeks since then. I was ghosted. Pretty unprofessional for inviting me to another interview verbally and not following through. If they went with another candidate, I would've understood. A rejection is better than ghosting.
