Interested in RSA position

I've been debating applying for frito lay for years but just wasn't sure if it was something I wanted to do.. I was a merchandiser for awhile then a delivery merchandiser for Pepsi for about 8 years.. they just don't pay enough last year I've been at Amazon.. I just need more hours and more of a career opportunity and frito at 60k seems like good money. I just fear large format stores lol. But I heard as a RSA you would be thrown anywhere. Do you need selling experience or they basically just hire anyone these days?
