Literally everything I learned in my high school careers class was useless because the world changed so much because of the internet getting more and more mainstream. Was told to keep calling and asking about applications; nobody actually answers the phone. Was told to collect and fill out applications in person; everyone moved to online-only applications. Was told to dress like I'm going to church for interviews; most interviews I've had were group interviews and 90% of the other applicants just wore jeans and t-shirts. Was taught to meet the higher ups so they would get to know me; the higher ups aren't even on site except maybe once in a blue moon because something went wrong.
