My last job, they didn't fully train me because tjey were "too busy", then when they paid for me to do a live online course at work, they gave me the incorrect machine to work on and the instructor was scolding me the whole time because they couldn't properly give me directions, while the other students were poking fun at me.
Not only that, but I had to mute my mic because because my coworkers kept shouting and using loud machinery in the background.
OTOH I've always found on boarding to be infuriatingly slow and long winded...Yeah i get how to use these systems, I understand the basics of your work flow now let me fucking do some actual work!
My most recent job took SIX WEEKS before they started allocating work to me. And they didn't even have a proper onboarding process - they just sat me down in front of a desk and didn't know what to do with me. I ended up heading over to their manufacturing area and spending a couple of weeks helping people fuck about fixing things because I was so bored.
I remember my first job at McDonald's, and this was literally their onboarding. Didn't watch any videos or anything. They just asked:"you know how to make a burger right?" to someone who never eats at any fastfood place. That was a rough week
