Super nervous about possibly getting my first job. Advice?

Good morning, afternoon, or evening depending where you’re reading this from. So about 6 days ago, I applied to a Target in my neighborhood and received a HireVue interview. Waited for the five business day period to pass and I called. Unfortunately, no one in HR was available but no worries they told me to call back Monday which I will. But, these past few days I’ve been overthinking, if I get hired, how the ambiance in the store is going to be? I don’t usually go to that location and I read some of the reviews but I don’t want them to totally reflect the store and the vibe. Maybe this is just me overanalyzing things? It would be my first job and the way I’m trying to tell myself is “you’re there to work” that’s it. I’m trying to be a little realistic because I know every workplace is different and it’s a retail job so.. I just needed to hear from people with more experience. On the bright side, I’m still grateful and excited for the opportunity of being considered. But I’m super nervous and a tad scared, I just hope out in the end it works out alright in the end.
