I applied through university. The process took 3 days. I interviewed at Duke Energy in Sept 2017
Interview
Applied during campus career fair. Got an email for on campus interview few days later.
Interview was held by an HR personnel and an engineer. Most interview questions are pretty general and some were related to college experience (went through your resume, previous work experience, why engineering?, why Duke Energy?), nothing technical.
Got an offer approx. a month after the interview.
Definitely more of a behavioral interview. They ask various questions on how you dealt with certain situations. They also ask questions regarding your resume and who/how certain organizations are led.
Interview questions [1]
Question 1
How did you handle a situation where a teammate or co-worker did not put in the same or right amount of effort.
