Question: "I went to the Career Center to look around. I was very disappointed to see only 36 jobs listed within 45 miles of my home and I searched all job categories. [...] If this is all of the current positions available, what benefit is there to go through the application/interview process to utilize an Account Executive when I can apply for the positions myself as I can on careerbuilder which lists hundreds of available openings?"
Answer: No, those probably aren't all jobs available in your area. In most cases, the job orders that AppleOne account executives are working will be filled before they ever get posted to the Internet. If a job is open long enough to be posted to the Internet, it's because it is proving particularly challenging for the AE to fill. This might be because the client company has a requirement that is particularly unique, or because the AE just hasn't met with very many people recently who would be suitable fits.
For this reason, you would definitely want to apply to AppleOne, as that will allow us to consider you for the vast majority of positions that never get posted to the web site. If you have particularly marketable skills, it would also allow your AE to "Take You to Market," that is, get your resume to some of our clients who might not have a job order open with us currently, but who your AE knows is always looking for people with your skills and experience.
Also, to address your question about why should you do this instead of that. You should do both and anything else you can think of to find your dream career. Our goal is to find rewarding career opportunities for you, and we help over a hundred thousand people do that every year. But, it's your career. You ultimately have responsibility for your success, and AppleOne is but one very good tool of many that you should be using.
