Generally speaking, it's ok. The school's duplicate checking is also to test the originality of your paper. Just submit it for double checking. Don't worry.

If the deadline for submission has passed, is there any chance to rewrite and reply? It's really painful Will the company and the school make things difficult after the second interview? I suggest you ask your brothers and sisters how your school handles papers.

Graduation thesis is not only a prerequisite for graduation, but also a summary of what you have learned in recent years. I suggest you treat it with caution. If you really don't have a good knowledge, you can't let it affect your graduation. You can't let your youth be wasted. You should hand in your paper if you can.
