It is best to post photos, of course, if there is no hope, you can not post them. If it feels good, don't spare a photo. After the interview, I won't give you my resume, and there's no need to bring it back. If it is a small company, usually unqualified resumes will be ignored. Large companies may keep files for a period of time, and others may turn over your resume after taking over, but it is unlikely.

Theoretically, I should be able to get it back, but in fact, I can't. I lost a lot of copies of my ID card and diploma when I applied after graduation. I suggest that you submit only one resume when you apply. If the company is interested in you, I will hire you after the interview and give them some copies of the certificates that should be handed in.

Before applying, you should mark the words "This copy is only used by a company" on the copy of your ID card and diploma, and then you don't have to take it back. If you don't write, you'd better take it back Although the chances of them going abroad with your certificate are relatively small, you should be careful.
