The process was pretty long, it contained 12 questions (2 of which were more relocation questions). The interview was through an online program, but I didn't have trouble accessing or figuring out how to use it. The interview wasn't live but they did use real people to ask the questions.
I applied through university. The process took 2 months. I interviewed at bp in Oct 2012
Interview
I applied through campus career fair services and got asked to do an hour and a half interview. Thirty minutes was behavioral questions, thirty minutes was a technical question, and thirty minutes was general information given by the recruiter or questions that I could ask the recruiter.
Interview questions [1]
Question 1
The technical question went something like, "What problems would our company face when shipping oil in a pipeline over a mountain range, then down a valley? Where would areas be with high pressure and low pressure? Show us all the steps you take to answer the question."
