You have to know what to watch out for when you screen your potential applicants. Here are some tips to make sure they are who they say they are:
a Check the application for errors and any information that strikes you as false. Always ask the applicant to clarify suspicious data and engage them in a conversation. Most lies or attempts to hide information, will become apparent.
a Ask for a complete history of residence. If they have moved long distances numerous times in a short period, ask why.
