CV
I've had people interview for a job and when I tell them that their skillset is not a good fit they would blurt out that they were a Christian and then tell me why that would make them a better employee than better qualified non-Christians. That argument didn't go very far with me since I'm not a Christian but I assume that these Hail Mary moves do help them at times. I've even had it suggested that I join a Christian church just for the business connections.
In any case, I really want to know as little as possible about the personal lives of applicants; generally after they are hired we get talking about politics and religion but by then we are usually friends and can disagree without thinking less of each other.
My ex-brother-in-law devised a system for disclosing his religion, politics and sexual orientation because he knew potential employers could not ask. For example, he would mention going to mass so the interviewer would know he was Catholic if the interviewer was familiar with Catholicism and knew Catholics called their worship mass; he would mention volunteering for a left leaning group that few conservatives were familiar with so if the interviewer was liberal he would score points; and would mention that he doesn't have any kids "that he knows of." to make it obvious that he is straight.
