Supervisors overseeing a facility's operations and maintenance team, coordinating schedules, reporting to facility management, and ensuring service-level compliance.
Screening looks at prior facility-type experience and team-size managed, since supervising an O&M team in a hospital facility is a different job from supervising one in an industrial plant even though the title is the same.
Relevant prior facility-type experience (commercial, industrial, hospitality) should be specified where it matters to the employer.
