Replying to Caddying

So i am an 18 year old (former) high school student in look of a summer job. there are a few country clubs in my hometown of belmont massachusetts and ive been considering getting a job at one of them. i have a part time job at a local ice cream store, but im looking for something better paying and more full time. Has anyone ever caddyed before? i have absolutely zero golf experience so i have very little idea about clubs or shots or anything like that. as a 3 sport athlete i feel more than confident about carrying around one or even two bags for 18 holes. my only concern is not being able to answer questions about golf. so any help would be appreciated

Cliffnotes - if youve caddyed, please help give someone who has no golf experience tips about it as a possible job
