They frequently posts a job description for a certain position and it often has a word count of up to 550 words or more describing the job. They typically pay $22/hr for it. The job reads like you are doing everything from the Janitor to the VP and everything in between!
I get calls from staffing companies pushing engineering jobs at that level of pay, no benefits - for 35 years experience, PE license, several industry white papers. The calls are likely from boiler rooms in India.
