Just to add a different perspective. I had an interview where AO was too focused on taking notes. His head was down for basically the entire interview and he wrote down practically everything I said. Despite this it didn’t seem like he was actually paying attention. He just ran down the list of pre-prepared questions and sent me on my way.
I don’t think it’ll hurt my application really but I also don’t think it’ll help much. Sometimes you’re just another activity to cross off on a very long to-do list, I didn’t take it personally.
