I applied through college or university. The process took 2 weeks. I interviewed at Canadian Natural (Calgary, AB) in Feb 2018
Interview
Interviewed with HR rep and an engineer. Very typical interview questions, greatest strength and weakness, conflict resolution, tell me about yourself. Overall a good experience, answered all my questions and were friendly.

Interview
Mostly behavioral questions, not a technical interview. Interviews are very relaxed and friendly. Typically will have an HR person and the engineer you will work with interviewing you. Mostly ask you about past experiences and ask you to elaborate.
