If you are a college graduate, keep in mind that you can use their placement offices years later when you may be unexpectedly out of work or returning to the area after living out of state. Be sure to call your former alma mater to find out their policy on job placement and referral. Some jobs may be entry level, but if you are suddenly needing to work, it is worth checking. I have used college placement services, and my experience has been that the majority of jobs are entry level to mid-level in pay scale. This may not be true in a larger community since my experience has been local.
Many companies have a bulletin board containing job postings within their company.
Area government offices, hospitals, and schools usually have bulletin boards that are accessible to the public. Also, friends working on the inside of a company are a good source of information about current job openings. However, while you are there, it's a good idea to ask them if they are aware of any other companies that may be hiring. Keep on asking people you come in contact with. They will admire your persistency.
