Tips for working in hospitaly industry

I'm just looking for some advice in this field. I'm a recent grad but don't have as much experience as I would like. I guess I'm more just overwhelmed because I've been applying to jobs and feeling pressure from my parents to get a job so they can some help with financials. By the time I actually get to the interview I'm already nervous and I don't talk a lot so I think I don't get hired because I don't give off an up beat personality like most companies want. Should I start preparing answers to common interview questions or will that come off as robotic/obvious that I prepped that? Does it help not to think of so much as an interview but a regular convo about the field I'm trying to get into? Anything helps
