In reviewing over 50 years’ worth of data on job applicant sources, the researchers Zottoli and Wanous have found consistent evidence that “inside sources” (employee referrals of friends and acquaintances, rehires of former employees, transfers from inside the organization) provided people who performed better and remained on the job longer, on average, than “outside sources” (advertising, web or employment agencies). Furthermore, employees hired through inside sources tend to be more satisfied with their jobs, likely because they have more realistic expectations about what the job will entail.
- I believe that there are likely two primary reasons for the superiority of “inside sources”:
- Such applicants receive more accurate information about the job and so “prescreen” themselves out of jobs for which they aren’t suited.
- Recommenders will assess “fit” before suggesting someone for a job.
