Which pre-employment screening instrument gathers a large amount of applicant biographical information for relatively little cost?

Reference checks involve contacting previous employers or other references to verify an applicant's work history and qualifications. While valuable, this process can be time-consuming and may incur costs, such as phone calls or hiring third-party services, making it less cost-effective for gathering initial biographical data compared to application blanks.

Background checks require substantial resources, including financial investments in services that verify criminal records, employment history, and credit scores. This process is generally more expensive than application blanks and does not primarily focus on gathering biographical information directly from the applicants themselves.

Job interviews are interactive sessions where employers ask candidates questions to assess their fit for a role. While they can yield valuable insights, interviews are often time-intensive and can incur costs related to scheduling, conducting, and possibly hiring additional staff to assist, thus not being the most cost-effective method for initial biographical data collection.
