Every txt and phone call, every email and letter sent to your address along with every utility bill (list goes on) has been saved since at least 1999/2000 to present day. People like Bernie went to jail because they pushed back and it was all because of this....
I'm kind of an old guy but I remember having interviews, just shooting the shit with the hiring manager and maybe a team lead present. Whole thing would last about 30 minutes and end with a handshake and an offer in 24-48 hours or a call to let me know I wasn't chosen. Between 1999 and 2019 I worked for 5 different companies and the interview process was basically the same. These were not small companies either. If someone told me today I'd have 6 interviews with homework, I'd tell them to fuck off. Thank goodness I retired......
