I rarely ever take referals and have declined a trusted member and very nice guy (I found out later) solely because he used a referral from a provider who's past referrals have given me a hard time in session. Personally referrals interfere with my screening process but I respect and understand the purpose of them and will be more than happy to give them but very hesitate to take them.
My very first BR job was with a group of mature woman and I had to work for free at least one shift with each provider with a focus on screening. I was asked what I thought of each caller, if he was truthful, what vibe did I pick up, what did I think he would look like, ect. There was no calling back at work, most calls were private, no referrals. I was so resentful at the time but now I realize how lucky I was to learn important skills from seasoned providers.
