The results: For white collar jobs, referrals are number one.

Almost half (46%) of those jobs were filled by referrals, according to a survey by the Inavero Institute for Service Research.

Why? According to a lot of companies, getting a reference from an employee you trust is one of the best ways to predict a new hire’s success.
