19 years old-need a JOB!!!!!!?

Try applying to places that are more local oriented and/or places that clearly are hiring. Also you may need to revamp your technique to interviews as you may be giving away bad impressions. Try practicing with your parents, or your friends and just go to the interview confident. Be confident throughout the whole process and another good idea is to ask those who have had several jobs, or experience such as your parents, for tips or help.
