There might be some experience you haven’t thought of, like volunteering, babysitting, extracurricular activities, etc. You don’t have to have experience to get a job, but other activities show employers a fuller picture of who you are. You can use that to show that you have a good work ethic, work well with others, that you’re responsible, etc. If you write up a resume, you can also use that to highlight other abilities, like computer skills, fluency in another language, awards, etc.
If you put together a resume, take the time to write a cover letter for jobs you really want, explaining why you want the job and why you’d be a great candidate. Enthusiasm and a bit of research can really help here. Learn what makes this company different, and express interest in that in your cover letter.
Look for jobs outside the beaten path, or internships if you can afford to do that. If you’re interested in any extracurricular activities, look for jobs that link up with those interests. For example, if you’re in your school’s drama club, you could be a counselor at a drama camp for kids. Or if you’re good at math, you could be a tutor. Consider starting your own business.
Ask people you know if they’ve heard of any job openings. Ask them to keep you in mind if they hear of an opening that would be a good fit, and to put in a good word for you.
Be enthusiastic. Once you’ve dropped off your application/resume, call back after a reasonable amount of time (maybe a day or a couple days) and let the hiring person know that you’re calling back because you’re very interested in the job. In a lot of beginning retail jobs, many people won’t bother to do that and even this little detail can set you apart. Once when I was a hiring manager, someone kept calling back to “check on their application.” Ugh, don’t do that. That person didn’t add anything to the discussion, or give me any reason why they wanted the job or why I should hire them. Be friendly, polite, and enthusiastic, and remind them that you’re interested in the job and would be a great candidate.
After the interview, call or e-mail to say thank you. Lots of people neglect to do this.
If you need any help putting together a resume, send me a PM. Good luck!
