Oracle Hardware Engineer interview questions

The campus recruiter distributed my resume to several hiring managers and within a week I got phone calls from several managers. They all basically told me about what their group does and learn about my technical background. Then if you show interest in their positions they will tell recruiter to arrange an onsite interview. During the onsite they didn't ask too much technical questions but just talked to you further by introducing their group and asking more details about your phd work and course work.
