Although the above noted information can provide you with very detailed information, it is usually only available from larger companies. Yet nearly every size organization has a third type of information that can also greatly enhance your job search. This is one type of information that will not usually be available through public access, so it typically requires a direct call to the company. Ask to be connected to the Marketing Department, then ask if they would please send out some general marketing information on their company to you. This could be in the form of general company information or specific product information.
Most companies are happy to oblige.
Do your best to become familiar with the company's position within the marketplace and how they position themselves with their customers. Ironically, most students don't attempt to access any of the above information until after their first on-campus interview. But if you are serious about your job search, do your best to acquire the information before you make contact with the employer or its representatives. Job search is a two-way street. Don't just go begging for any job.
