Dear friends, I just received an email asking about the interview results. Do I have to reply?

Personally, I don't think it is necessary to go back. The content of the email says that I will contact you if there is any news, and generally I won't wait so long to inform you if there is any news. Under normal circumstances, I will be informed soon, because it is difficult to recruit the right person, so once the company thinks this talent is good, it will be determined soon.
