This is the best way to avoid interruptions. The employment application is a very important part of the recruitment process. A standard application from a business forms supplier or catalog is fine. There are two statements on the application which, when signed by the applicant, become very significant. Everything in the application is true, and if not the candidate can be released.
Permission is given to check the references.
Checking references is very important, but it requires a skill level on the part of the reference checker to get the facts. Your chances of getting the true story are improved when speaking with a person you know. It is good idea to circularize key people in your organization with the names of the organinizations with whom you will be checking references. Maybe someone in your firm knows someone at the company. If a candidate says they are certified, or they had outstanding grades, mak sure the facts are correct.
