I took the SRO Success test at an Entergy plant in July. It consisted of the things talked about above. The process started at about 8 in the morning and we finished up about 4 in the afternoon with a 1 hour lunch break. I'm not sure how I did on the testing, since they wont reveal your final scores, but i did get a job offer so I must've done ok. I talked to the HR rep administering the tests, she said they were doing these exams in all the Entergy plants but one, and that more and more companies were utilizing their services over the last couple years.
