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.

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 No job offer will be withdrawn, and no adverse action will be taken against any employee, based on the results of a criminal conviction background check, without an individualized assessment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.
