Each year Graniterock recruiting teams visit targeted colleges to recruit qualified students for our internship program. Graniterock team members who are graduates of the targeted schools are invited to help recruit students at campus events. We also encourage students to contact us directly either by phone or a personal visit to discuss internship options. Typically, students work during the summer, or part-time during the school year. Each student works closely with a manager who provides orientation, general training, and periodic feedback throughout the internship.
