How do I get a job as someone in hs

First try asking family, friends and neighbours if they need help with anything or thwy know someone who is willing to take you in to work
This is one of the best ways to gain experience easy
How old are you?
Since its summer lots of shops are offering summer jobs for teenagers go to their websiye and there will probably be an application forum
Since your a teenager you will need to write a motivation letter
In a motivation letter you state your age why you wanna join this job what are your strengrhs and what experience you have ect
