If you are limiting your search to the local area, sometimes the best way to find advertisements is to go directly to a company's website and search their career listings. You can find a list of the largest employers in Central Florida here.
If you are interviewing with a large company like Disney or Darden, you can easily find articles published about their activities and initiatives. Search a database such as ABI-Inform or Business Source Complete for such articles.
If you are interviewing with a small company, the odds are poor they will have generated articles in national or even local publications. In such a case, the best thing to do is research the industry so you can carry on an intelligent discussion about trends and issues relevant to the company.
