how do i get this NA job?

hi everyone, right now im finishing up my ast of my pre reqs for my 4 year nursing school a&p2, micro bio, philosophy, and history classes i plan on getting my bsn...i really want a job at my local hospital as a na i want to get in the hospital and start working with patients. im not a cna already because the classes never work with my classes and its really hard to find classes around here. i dont have really any experience in hospitals but i have taken care of my granfather who had cancer,myasthenia gravis and empyzema. i also helped take care of my grandmother who had alzheimer's and had a peg tube in. i know my way around a hospital pretty good and how to use most things since i spent a ton of time in them over the years with family. i am cpr/aed certified also in basic first aide. oh its in the oncology unit.

this is what the job says online:

high school diploma or equivalent.

nursing assistant course and cpr required after employment.

on-the-job training acceptable for non-professional, non-technical care of patient under supervision.

previous experience in hospital or nursing home preferred

how can i up my chances of getting the job?

should i try for a different job? such as a escort aide who moves people for test etc?

do you think i have a chance in getting it or no?

should i apply online or in person? if in person how do you do that at a hospital?

does it sound like they will train me to be a na on the job? (might be a stuid question i just wana make sure haha)
