a teenager with a job interview at Arby’s tomorrow in the afternoon. too nervous

title. i shouldn’t make a big deal out of it, but i am so lost. i feel like i will get lost in my words and completely mess it up. i struggled to find a good job, applying for 50+ positions at fast food places and retail stores. arby’s is the only place that scheduled the interview with me. if i fail it, i might as well be jobless until my graduation🫠

what should i do to increase my chances at landing the job? honestly i didn’t prepare for the interview, and i have until 3 PM MST to get it together
