No one's hiring

Fresher with good and relevant internship experience, I'm getting rejected for some job roles where I am overqualified(not being cocky)

For job roles, I'm excited about there's work ex needed but one seems to be giving me the job, how will I get work ex? I have sent LinkedIn DMs, cold emails and what not but still nothing. I am getting rejected or worst no revert.

I have worked and want to work in the marketing&brand side preferably learn from senior folks in the industry but seems impossible in this market.
