what is the best way to get a job? i tried as a custodial officer but they said i was too skinny and young to get awarded the job but on the vacancy it said you have to be 18 or over and no qualification requirements needed

You don't to force yourself on something that won't really work. There's a lot of opportunities around so instead of wasting your time thinking aboout, apply to other places because maybe your destiny wants you to land on a better one.
