A majority of job hires come from personal referrals. You should try to make sure that any job you apply for is applied for through a referral. When you go into an interview as a referral, the interviewer automatically is in a position to think more highly of you, because you’re borrowing the social credibility of the person referring to you. The reputation and rapport the person referring you has with the interviewer is partially extended to you as the interviewee. You’re walking into the interview with the interviewer having a partial bias toward liking you already because you were referred by someone they like and trust.
