Because if the future is secure, the company will read your resume first, if it doesn't meet the requirements of their company, it will call you for an interview, and if it doesn't, it won't call you. As for what you said, there are fewer companies reading your resume. I think the reason is that your resume has been suppressed. New resumes appear every day. It's not like the old resume sank. I think refreshing your resume is good for you.
