Easy. I was in just 1, but i heard what they were all about. They happened weekly.

This boss mainly ran his hardware renting business. The software for that hardware was often optional, but they developed and sold that as a seperate company with almost the same name.

The guy had no idea what development meant. What it means to test. Everything he knew was hardware, and it just never really clicked. This means that bugs and non linear development cost for a feature were confusing to him to a point that when brought up or conflicting, he would look confused, and walk out the office without another word.

This guy would bust in, usually monday morning and call a "meeting"
They gather in the lunchroom as thats the only place everyone fit, and the guy would go on a 3 hour monologue on god knows what.

It was never positive and always full off complaints and idiotic ideas that the senior developer had to break down until as if talking to a big toddler, on why they do not work.

As a result everyones day started mizzerable, nothing got done. The software package was full of logic flaws. And everyone wanted to quit but didn't have the energy to invest in that.

During that internship 1 guy was fired. In the 2 months he was there he litterally did jack shit. And if he did anything it was the bare minimum, committed broken but compilable, and then wait for revision requests.

Yeah that place was a shitshow. I loved it, but never again.
