The employment application form that you use should have space allocated for candidates to provide detailed contact information for the people that they are using as professional and/or personal references as well as a section dedicated to the individual's work history. It's up to you to determine how many references to ask for and how many prior jobs to request details about.
Typically, companies ask for between three and five references, and require the majority of them to be professional references. The form should provide blanks where applicants are asked to provide the first and last name for each reference along with space for two telephone numbers where the person can be contacted. Some employers also request mailing and email addresses for references.
For prior work experience, it's common to ask for places of employment for the last five to ten years, depending on the type of position you are hiring for. The work history section of the application form should have space for applicants to fill in the name of each company, job title, description of duties performed, dates of employment, supervisor name, and reason for leaving.
