While in college, I often would take a drive around areas that I potentially would want to work and see names of companies that I never had heard of before. I’d then go to the library (or dial up on Prodigy and later AOL) and see what I could find out about the company or location.
Today, it’s so much easier to just rely on the internet for job searches. I challenge you to take a drive through a business park, visit an office building, or walk through a downtown area to find local companies that you may not have heard of. I call this method searching the outer-net.
Even with the internet, many companies will not post jobs nor much information about themselves, especially if they are a local company. You may miss out on getting to know about a company that may have a job offer if you stick to just the internet for your search.
