"At an interview for a security guard position, you may be asked about your criminal record, availability, and ability to handle difficult, stressful situations on the job. Employers will look for security guards with clean backgrounds who can work obscure shifts and remain calm and collected during potentially dangerous situations. The certification requirements for security guards vary by state, so be sure to read up on any training you must do or registration you will be required to obtain upon receiving the job. To ensure you can be trusted to protect company assets, most if not all employers will require you to undergo an extensive criminal background check during the screening process."
