For me (as a programmer) it really varies a ton. I used to put in insane stretches, due to the medication I needed to take in the past and that is how I got used to things in college.
Now I work more regularly, but still can put in a solid 6+ hr day most of the time, and yet some days… yeesh I’m lucky if I can get a third of that. So I work more on other days to compensate.
Cloud eng with ADHD here. It really varies between 30 minutes to 16 hours, both extremes being rare
Some days I feel I’m getting absolutely nothing done, but also quite recently I was hyperfixating on a project and would continue working off hours with a glass or 5 of whiskey because I was having too much of a blast
However I’ve been reminded before by my manager that the random chatter and stupid meetings are still part of work, and while there’s optimizing that can be done, I shouldn’t count them as slacking so eh I guess 8 hours a day it is then.
That’s a boss that’s living in reality, congrats!
I feel this so hard! 😁
