There is no doubt nobody fully understands the requirements (in our industry?) and that's good advice, being pragmatic. However, even when the requirements are clear, it's a pretty chaotic process which is hard to follow. I wouldn't discard this as simply being a style issue. This person seems pretty nervous when discussing things, so there is some struggle. I can try to clarify the requirements for everybody's sake (including mine). Please don't label this person as the 'ADHD coworker' though.

Thank you, I'll try to read more about ADHD. I just wanted to clarify that I have not determined this person has ADHD or anything else. They have said it. I'm just describing the behavior and mentioned ADHD as maybe that's related but it could very well NOT be. In any case, I appreciate your advice, thanks.

Point taken. However, saying "X app connects to Y app, that's for sure" when that is NOT the case is wrong. Period. Facts are facts.

"We should do X because things are like Y" when things are like Z, you just have to check the code and show it, that's a hard fact.

Maybe I should have said "remembers facts incorrectly" instead of "opinion". Sorry.

Re: having worked in a famous SV company doesn't mean everybody should get a free pass to say B.S., right? I'm sure your FAANG company isn't made of perfect human beings (or has a perfect hiring process).

> mean everybody should get a free pass to say B.S., right? yes, but you should accept that this is not a purposeful action and it is because of a mental state condition.
