EPAM Systems Linux sysadmin interview questions

Recruiter was good. Swift, professional, with excellent communication. Simple and straight job description. It was all good until the "technical" interview. The person who joined for the interview demanded I turned the camera on but he didn't. I can manage strong and weird accents but his Indian accent was so strong that I had a bit of a problem to understand him some times. Without any rapport he jumped directly into business (fine for me). But I was not asked a single question that I would consider technical. He was asking pretty broad and ambiguous questions on automation and security that I describe below and despite me explaining that I would need some more specific questions, he just kept rephrasing the same question until time was up and he said he had no more questions.
