What's a resume farm? I'm actually pretty new to looking for a job. I have been in the military for almost a decade.

A resume farm is an entity that collects (farm) resumes. The job postings are most likely taken from other sites. Salaries are inflated to make you want to submit your resume.

Are there any reputable job sites? I have mostly been looking for positions posted on sites such as clearancejobs.com, but I usually apply directly through each company's website.
