SLB Intern interview questions

They came to my school to do an information session. I turned in my resume and received an offer for an interview a couple days later. The interview was the next day, and i'm currently still waiting on a follow up (has been about 4 days).

Apply on campus career fair. Waiting in line and get a short interview with a recruiter. Basically asking about project and previous experience on resume. Questions are about details of my projects. So it may be helpful if you know what you did well. However, I didn't receive any reply.
