I feel at a loss as to when I'll be able to get a job.

I am a final-semester student hoping to land a job in the beauty industry. I'm not sure if it's appropriate to post something like this here, but I'm writing this out of sheer frustration. I want to work for a beauty brand, so I've been participating in extracurricular activities and managing an Instagram account. However, I keep getting rejected. I'm losing confidence as I'm failing to get entry-level positions and even internships. It's so frustrating because I don't know if this is due to my school or something else. I only have my final semester left; will it be possible to get hired within that time? If I keep working hard, I'll be able to land a job, right?
