> Sure, it would be possible

I have to be blunt, you have no idea what you are talking about. I am just going to say this: A terminal app is completely at odds with an online web client. If the interviewer is as clueless as you are, that explains two things:

- I was never going to pass the interview in the first place

- I was never going to get a reasonable conversation from this person, no amount of communication is going to solve incompetence from the interviewer's side

Corollary:

- Gross negligence from the company for assigning this interviewer
