Actually, I've had more than one interviewer comment on it saying it "shows (I'm) prepared" since many people don't bring anything to write on and sometimes have to ask for a paper.

As for whether that could be a bonus in getting hired? Meh. 110% depends on the field.

If the question is "will asking unnecessary questions and writing down answers help get this job" then I'd ask if the interviewer isn't prepared for a couple innocuous questions, then it shows a severe lack of preparedness on their part and I'd question whether I want to work for a place where someone gets shook by their underlings daring to question them.

I fully admit I am already biased against nearly any company that I would be interviewing at, so I'm already more willing to get confrontational in interviews if I feel I am not getting the respect I deserve (you know, the basic human decency of treating every random person you meet as an equal until they prove otherwise worthy), and drop them to keep looking than the average person. I'll eat ramen and peanut butter sandwiches for a few more weeks if I need to. I've walked out of interviews before.

I've walked out after the opening "greeting". "alright let's make this quick, I've got a dozen other interviews today" okay well if that's how you treat someone here for a simple interview I can't imagine how you treat your employees on a bad day, get fucked. I literally said "excuse me? You don't talk that way in a professional setting." and left.
