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

Just keep on looking for a job. I was ignored 5 times in different companies and it made me so depressed. I'm about to give up until I met my classmate who also tried to apply 7 times and luckily found stable job right now. I got also a good position on the company where I am working right now
