Very smooth and nice interviewers, do lots of research and be yourself, and it won't be too hard to get. More STAR-based questions so practice similar questions for the interview.
I applied through college or university. I interviewed at ConocoPhillips (Midland, TX)
Interview
The interview was very friendly and chatty. Two interviewers and they just wanted to have a conversation. They wanted to learn more about me as a person rather than a candidate.
Interview questions [1]
Question 1
Basic questions were asked, why oil & gas and what are my interests in in career.
Online interview, friendly people. No difficult or technical questions, more behavioral questions like describe a time you had to lead a group of people...etc. I suggest to read on the company's operation and just be relaxed and friendly.
