PIMP your way to a new job

One guidance on job sites and recruiters.

Often job sites postings actually lead to recruiters, not the hiring company.
Often multiple recruiters are trolling for the same job (i.e. whoever sends the winner gets the bonu$)
Recruiters don't like to submit you if another recruiter has or might have submitted you for the same position or if you sent a resume directly to hiring company. But sometimes you can't tell if you are talking to a recruiter about a job you already sent directly or via another recruiter (or sometimes via a job website which doesn't reveal the company). Reputable recruiters will tell you where they are sending your resume. Reportedly if your resume arrives at the hiring company twice, your resume could get thrown out.

This can get confusing. Don't worry too much. Hard to tell if it is better to have a PIMP or go directly.
