Shell Summer Intern interview questions

The application first start from on-line application form. And then you will expect 2 emails with 3 on-line assignment. The first 2 is about decision making and personality. The last one is time constrained (finish within 18min) math problem. About 2 week later, I got a face to face interview. The on-campus face to face interview is pure behavior questions and some general questions. Since it is the alumina who conduct this interview, so it is pretty relax.
