I just got scheduled a 1-hour interview call from Oracle for next week. I don't know if someone already has their interview with Oracle recently and can give me a guide on which part I should brush up on.

I applied through my university career fair by filling out a brief form and handing them my resume. After about 2 weeks, they sent me an email to setup a phone interview. During the interview process, they gauged my understanding of various basic programming terms/paradigms. If you've been paying attention in your classes and are a strong programmer, you should do fine. Be yourself and do your best!
