I applied through college or university. I interviewed at ConocoPhillips
Interview
Presentation and follow-up questions, slides and formulas, no interest in formulas but lots of open ended discussion, of course the lunch part which is presumably the most valuable, make sure to be clear what you to do and why you want to work for conoco
Fairly standard in-person technical interview for subsurface professional role in Calgary. There were no technical questions per se, beyond ordinary questions about experience. They asked about salary expectations. Overall, it was a pleasant experience.
