Employers Overload interview questions

What process? Filled out application and told to be at work that night. No drug screen or interview questions. I was in and out the door in less than one hour. Said they had to run backround check but I don't know if they did or not. It was the first time I was hired in such a manner not to mention that I started that very night. No training, videos , or anything. I don't even remember doing any testing. They are just looking for a warm body and a pulse.
