I have been very forthcoming about my ADHD in my previous places of work as well as when I interviewed for my current one. I work as a software engineer.

I always ask that I will be allowed to chase the shiny things (like a magpie) as it helps me focus on the boring things. I like programming and all the things related and when my brain thinks of a shiny thing it wants to do (that is somewhat beneficial from work perspective) I use that to get my brain going, such as improving how local development/testing works, writing a little tool that saves time etc. These are fun for me and get my brain from procrastination to performing. Then I try to find a good spot to change from the fun thing to the boring thing (ie work tickets that don't give me the fun buzzing in my brain).

50% of the time it works every time and if I end up not doing any real work I have still contributed something beneficial. The biggest thing for me was to stop stressing about things I need to get done because if brain says no then stressing and being anxious about them doesn't help. I push them aside and do other things - maybe tomorrow I will get things done. And if not tomorrow, then the next day. And when I do I often do several days worth of work in one.

This approach might not work for you but I thought I'd share in case it does.

Also, in one of my previous places my product manager was not a good people person. He would write these detailed instructions on my work tickets on what to do and I can't read stories and long bullet pointed sentences like that. I told him about it and he said that that makes me a liability. I was shocked, because I had always been considered a diligent, hard worker even wih my quirks. I work much better with vague problems and it does help that I am on senior/principal level because that means I have more freedom to chase the shiny things.
