Depends on the person. When I was undiagnosed, I got away with it for years because under extreme deadline pressure for my projects I'd sometimes manage to pull it off really, really well. And, to my shame, I got pretty good at bullshitting my way through progress meetings.

The rest of the time, I was a right mess. Changed entire careers twice because I figured what I was doing just wasn't my thing. Turns out it was more fundamental than that, and I'm doing better now medicated.

I know others afflicted with ADHD who had similar experiences of flying just under the radar of being fired, before they found out what was really going on.
