The one time I got an interview offer and I blew it

I feel like a failure, every time when I apply for a job, I get rejected or ghosted all the time and I don’t even get an interview offer. But the one time when one job I apply for and had an interview to do and had to record my answers to the company, but I feel like I didn’t really do a great job. I was stumbling on my words and kinda got nervous and I don’t think I did my very best on the job interview.

Two weeks later after I’ve submitted my video interview, I got an email saying they aren’t gonna continue with my candidacy at this time. I feel disappointed in myself, because I feel like I’m not gonna get another chance because no one wants to hire or interview me.

I don’t know what these recruiters want me to do to get hired exactly. Do I need to get certifications, do I need experience somehow somewhere even though I’m a recent graduate, or do I have to move closer to the city for opportunities? I just feel like no matter what I do it’s never enough. FML
