To everyone else, no one is withholding stimulants. I'm just working to confirm the diagnosis. ADHD is not an emergency unless there are safety concerns, in which case I do truncate my process. Also in theory, people could be very good liars/actors and research/ask people in the medical field what to say and how to act to convincingly project ADHD and get a stimulant. In my practice, the severe case of ADHD where a person can't even string a sentence together and has no other confounding diagnoses or potential contraindications is very rare, whereas liars and embellishers abound. I also think a lot of the "spacey" ADHD sorts will give vague and overly general answers to most questions, which is why surveys are important to get a more precise handle on the problem.
In more moderate/clear cut cases, I literally tell people - ok, how fast can you get these surveys back to me? When you get them back to me, we can start a stimulant. Those who care get them back in a week.
OP, another tip I have to make your interview more concrete and help define treatment goals is to ask about practical things - how's your driving? are you someone who constantly needs their phone/keys/wallet/ID replaced? how often do you double book yourself? are others frustrated with your behaviors and if so which? are there financial or other "costs" to your forgetfulness? If there are a lot of "no" answers to the above, it may help people realize things aren't so bad and themselves question if they need a med.
