Just after the interview, the personnel director said it was inappropriate. I said please return my resume. The supervisor said that I didn't understand the interview etiquette and tore up my resume. Is that really the case? Well, if you bring your self-made resume to the interview, you have the right to ask for your resume after the interview, because your resume is self-made; If the interviewer prints your online resume or electronic resume, then you have no right to ask. But whether it is polite to ask for your resume back or not, I think it is very impolite for the interviewer to tear it up in person, so the company doesn't have to go.
