I applied through college or university. The process took 2 weeks. I interviewed at SLB (London, England) in May 2016
Interview
First met with the college recruiter with some general information sharing about the companies newest technology, followed by some general interview questions and some brain teasers. The recruiter was very friendly and offered several positions available for me to apply for, although none of them fit what I am studying. I thought I might as well give it a chance, but as expected I messed up the technical interview through Lync completely as my area of knowledge is rather irrelevant. After that, the college recruiter still is willing to offer me another interview for other positions and tried to motivate me which I am super grateful for, but I have already accepted another job offer. Was the nicest recruiter I have ever met.
