I am wondering if it is okay to write down a list of questions and ask them at the end of the interview while seeming professional?
I feel like this way, I can assure all my questions are being answered and I don't have to fumble with thinking/rewording the questions in my head. Say, the questions are tucked in my portfolio along with my resume, references, etc. so that it does not look messy.
My second question is how many questions do you ask at the end of the interview?
