xo_kathy is right. With job search engines like Monster, CareerBuilder, HotJobs, etc., employers get hundreds to thousands of resumes as soon as they post a job. It is almost next to impossible to go through every single one of those resumes. Especially if they are a smaller company with maybe 2 or 3 people in the HR department. Many will have a computer search for keywords in your resume and unless the computer gets a hit, you won't get a phone call. That's why people say it's so important to have keywords in your resume like sales, bachelor's degree, management, etc.
Also, the Florida job market is tough right now (as it is through out the US). People all over the country want to relocate to Florida because of the weather and just the overall social atmosphere. Basically, you're competing for a job with not only other Floridians who are currently looking due to either a lay-off or just generally looking for something new, but you're also competing with people all over the US who want to move to the Ft. Lauderdale area (the area is growing rapidly with people transferring there). It's a tough market there. Believe me, I know from experience.

The best thing to do is network. This is how I ended up with my job; it was through a professor that I had become very friendly with who knew a few of the people I now work with and they told her that the company was looking for a marketing/public relations person. She suggested me and two interviews later, I was hired.
Do you know anyone is South Florida? Ask them where they work and if their company is hiring. Ask them to ask their friends.
Also, if you want to apply over the Internet, the best thing to do is apply directly through the company. Many companies have job listings on their web site so applying through that will give you better results than applying through Monster or CareerBuilder. In fact, many companies have stopped posting job listings on job search sites because they get so many resumes in from unqualified people who will just send their resume to any company that's looking for an employee (I'm not saying you're doing that!!!!

). They figure that if they post the job on the website, more qualified people will apply. A person with an electrical engineering degree will go to the IBM website looking for an opening because this person knows IBM specializes in computer engineering or a person who has worked in banking will go to the Washington Mutual website to find a job because they know WM specializes in banking/finance.
Put a list together of companies in the Ft. Lauderdale area that could possibly have jobs in the field you are trained in. Go to those websites and apply directly.
