After the interview, the interviewer returned my resume to me without leaving a copy. What does that mean?
This may be a euphemism for refusal. You should remember why he returned your resume. Try to find out. If there is no news for three or four days, there is no hope. It doesn't matter. You should reflect on what you did badly in the interview and actively prepare for the next interview. It is not necessarily a bad thing that this company doesn't want you.
