It is rare to receive an interview notice from some companies without submitting your resume. However, the following reasons are not excluded:

I once registered in the talent network and failed to submit my resume. I just haven't updated myself for years. This situation is exploited by some newly established or inefficient talent networks. Because I want to expand my appearance and show my popularity to the outside world, I record some resumes that are actually out of date on my website through some search channels. This is a kind of fraud to attract some employers to become their members.

The telephone number used now once belonged to someone else. This number was also registered on the talent network, but it was not updated later.
