I would find it very odd to save a string of questions until the end.
It's much more fun to engage in the conversation actively.
I'm not saying control the conversation. Good conversationalists listen more than they speak.
But having fun in a conversation is engaging in it. Not replying paragraph after paragraph, in my opinion.
In the context of interviewer<-->interviewee, though, I think it is generally more interesting to listen to the interviewee than the interviewer. It seems to me that the whole premise of the interviewer<-->interviewee is for the interviewer to get the interviewee to talk.
An interviewer’s job is to let the interviewee speak to the audience, even though the audience doesn’t get to directly ask questions.
In general nobody cares what the interviewer thinks, and we don’t want to hear them blab about themselves.
(This makes many “podcasts” unlistenable.)
