I applied online. The process took 3 months. I interviewed at Exelon (Clinton, IL) in Mar 2016
Interview
The whole process took place over several months in this order:
Phone interview, In-person Personality and Skills Interview, Aptitude Testing, Background Check, Psychological Evaluation, Drug/Alcohol Tests
The interview panel started with simple HR questions followed by in depth, three part questioning that was more personally and professionally specific.
