Approaching the referral ask

I would like to talk about referrals!

As a CSM on the job hunt I am told that my best chance at scoring an interview is through a referral, but how do I go about doing that?

Who do you ask? Where do you look? HOW do you ask??

Having been on the networking game for some time now I am still finding myself struggling with not just how to make the ask for a referral. But more importantly how to make the RIGHT connections that can lead to something.

So I ask, what works and what doesn't work?
