First Job Search Tips

Keep in mind that you may not get the first job you apply for, or the second... A job search can take time, especially if you don't have much experience. Here's how to ensure you're a top-notch candidate for the jobs you are applying for.

Be Persistent. Wait a few days, then follow-up your application with a phone call to the hiring manager reiterating your interest. If you have applied in person, stop in again and mention that you are really interested in the opportunity.

Don't Stop. Don't apply at one place and wait for the phone to ring. Complete as many job applications as you can, and consider a variety of positions.  小题1:   .

  小题2:   . Applicants who are only available for limited hours are less likely to get hired than those who are flexible as to when they can work. For example, one candidate for a summer job told the employer that they were only available on Wednesday afternoons and Saturday mornings. Compare that to another applicant who selected "any" on the Hours Available section of the job applicant and you can see why the second applicant got the job.

Use Your Connections.  小题3:    . Does your mom shop regularly at the store where you'd like to work? If so, have her mention that you're looking for a job. That's how I got my first job and how my brother got his first job at the drug store across the street.

Dress Appropriately. When applying for jobs, dress as though you had the job. If you're applying for a retail position, for example, visit the store before you apply to see what the staff is wearing.

  小题4:    . When in doubt, dress up, not down.

Don't Give Up. Job searching isn't easy, especially when you don't have much experience or many skills.  小题5:    . Your first job will be a stepping stone to your next job - and to your future career.

A．Don’t stop to look for a job.

B．The more you apply, the better chance you have of finding a job.

C．Be Flexible.

D．It will give you an idea as to how you should dress.E．You shouldn’t apply for different jobs at the same time．

F．If you have a connection, use it.

G． Keep trying and keep applying and you will find a job.
