Your “don’t prioritise fluency” is really good! Rather than focusing on being fluent, focus should really be on your answer! Another thing that helps me in interview situations is starting out by disclosing my stutter. It doesn’t take much time but is a huge relief or f my shoulders. Just a simple “hey, by the way, I have a stutter, so if I mess up words or take longer time to answer, it is simply because I stutter”. This lets you take control of the situation and I have only have positive feedback on this.
