The process is archaic and fucked up. Just contract it out if you can.
My only advice is this
Use 45 minute because it doesnt shrink like the faster drying ones do. So you can often get away with just mudding once (if you back butter the tape).
The lost time is not in the 30 extra minutes it takes for mud to dry. It's lost in the 2nd or 3rd coats hiding fucking tape lines. You won't be painting that day anyway, even if you use 5 minute. Trust me 45 doesn't shrink.
OK I have more to add:
Another thing, wide mounds can't be seen by the untrained eye. The eye only catches lines so stop fussing over sanding down gradual hump, unless you are in the kitchen or bathroom. (Walls with counters or cabinets being installed should be flush.)
If you sand anything, at the very minimum wipe the wall with a lightly damp sponge after. Don't get too wet.
Primer is for babies. Paints are so good now that as long as you prep the wall then you don't need to prime. The better the prep the better the paint. Even primer won't stick to dust. Plan on 2 coats of paint
Don't buy the cheapest paint. What you think you are saving in paint you'll lose in labor x2.
Texture hides most flaws but won't hide lines
Bring a 10 dollar step stool to the job site
Paint with a roller always on an extension. Can't express this enough. clean the roller 100% after done or you'll be buying another one.
Paintbrush and rollers you get what you pay for
Also, some guys in europe use a self dispensing back buttering tape gun that is so good it hurts my soul that it's not in America
Some floors get ruined if you clean them with paint thinner. Can never have too many drop cloth if you plan on doing a lot of painting. Thr brown Butcher paper is cheap from floor wholesalers or 4x the price from home depot. Plastic is my least favorite.
Use frog tape (green not yellow.) 3m masking doesn't beat frog tape
Always buy cabinets and doors pre-painted at factory no matter how good of a painter you think you are.

Not always true. In my hallway some clown did this shit and because of how the house was designed the natural light in the hallway comes in from the bathroom window and shines right along the hallway wall highlighting every hump, bump, and wave in their shitty job. One day I'm gonna have to spend a weekend fixing that shitty wall because it drives me crazy every time I look at it.
When I hire a drywall guy I check the work with a bright flashlight held against the wall and shine it in all directions. If there are big shadows we have a problem. It's also a good way to check the work of a tile guy and a floor guy (uneven floor tile is the worst).
Did they texture? What kind of texture did they use on the wall?
They used knockdown, but the shadows are way bigger than the texture.
