Exelon utilizes the standard "STAR" format for interviews - explain a Situation or Task, describe the Action you took, and describe the Results. None of the questions were truly unexpected - what you'd expect: questions about a time when you built a team, when you failed to meet a customer's expectations, or tell me about a time when you had to compromise instead of implementing your idea or method. If you have several stories prepared that can be generalized to different questions you should be fine. Also, it helps to throw in a story when things didn't go as well as they could have - this demonstrates your awareness of fallibility, your willingness to learn, and can show that you respond to the negative events in your career to make the best of them.
Interview questions [1]
Question 1
None of the questions were unexpected. By and large, the interview has the feel that it's a formality - they already know whether or not they want to hire you, or the hiring manager will walk you out to your car at the end of the interview (when the real interview begins).
I applied online. The process took 6 weeks. I interviewed at Exelon Generation (Clinton, IL) in Jan 2020
Interview
After submitting all the documents I had a phone interview. Following the phone interview I was flown to Chicago to take two Exams (POSS and BMST). After passing the exams I went to the site location on the following day for an interview with HR and two other Senior personnel. After passing the interview, I had a First Line Supervisor Exam/interview, and a week later an offer.
