Company policy prohibits unlawful discrimination based on race, color, religious creed, gender, religion, marital status, registered domestic partner status, age, national origin or ancestry, physical or mental disability, medical condition including genetic characteristics, sexual orientation, sexual identity, or any other consideration made unlawful by federal, state or local laws.

Mizuho OSI conducts criminal conviction background checks and drug screening through a third-party screening vendor which includes searches of address history, criminal convictions, court records, education verification, employment verification, and reference checks. In addition, depending on the nature of the position for which you are applying, a motor vehicle driving report, a credit report, and/or ID checks in other non-U.S. countries are also included.

Criminal conviction background checks will run after an applicant has received and accepted a conditional offer of employment. After a conditional offer is made and before any background check is performed, applicants will receive background check disclosure and consent forms under state and federal laws, such as the Fair Credit Reporting Act and the Investigative Consumer Reporting Agencies Act. Existence of a criminal record is not an automatic bar to employment. An assessment will be made about whether the conviction has a direct and adverse relationship to the job in question. No job offer will be withdrawn, and no adverse action will be taken against any employee, based on the results of a criminal conviction background check, without an individualized assessment of whether the applicant’s conviction history has  direct and adverse relationship with the specific duties of the job in question.
