Whatever you do, be organic. Not canned. Prepared questions often come off as just that. It’s fine to NOT have questions….if you don’t. Imo, a well prepared candidate would be just that, prepared, and may not have any questions.
But, I would make sure that’s the case, and let them know “ma’am, sir, I honestly have an understanding of the process, and don’t have any questions that havent already been addressed”, or something that acknowledges you understand. Vs a plain ‘ole ‘nope’.
No need to fill their precious minutes with fluff. BUT don’t hesitate to ask a question if you have one, or request a clarification of a point.
If they haven’t already addressed it, asking “when should I expect to hear either way” is a fair one.
I’m not on an MOC committee….those are standard interviewing courtesies, imo.
