Networking within the company you are applying to

When you apply for any position you should connect with your network to find out if you know anyone that works at that company.

Many times I receive personal emails from coworkers about friends who have applied. This strengthens your credibility.

I usually at least give these folks a call because I trust the opinion of a lot of my coworkers. It doesn't mean you'll get the job, but at least you will increase your chances of getting a phone call.
