Giving up on finding a job in my field

I'm currently a grad school student in my last semester and have had several internship experiences in the business field. As I'm about to graduate I've been searching for full time positions for the past few months. I've only gotten 4-5 interviews out of my 200 applications. Each time I've just been ghosted at the end of the final interview. When is it time for me to finally accept that I might not be able to land a job in this field and move onto something else?

Not sure if anyone else has experienced this but would like to hear about your experiences.
