not sure if your interview will be like mine in canada, but....here goes!
- safety is everything. have any experience related to safety? flaunt it!
- problem solving is a close second. anywhere else you worked, how did you solve problems, make things better and save the company money?
- show a strong interest in nuclear technology. research the plant you are applying to in depth.
- the interview i had started with a simple concept and took it as far as i could go in increasing technical detail- remember, sometimes the correct answer is 'i don't know'. they don't want people that are going to make stuff up, they want people who are willing to learn!
- having some background in the nuclear field, they went hard on me. can't promise you'll get this kind of abuse, but they wanted to know how i would respond under pressure. i had the 'good cop, bad cop' routine. one interviewer was very kind, the other was a complete ass. when i was thinking on a question, the bad one was practically yelling at me to hurry up and stop wasting his time. i just smiled at him and continued on taking my time. don't let them shake you.
- research topics like system chemistry and corrosion (rust). how do you prevent corrosion anyways?
- they pulled another fast one on me: i gave them correct information regarding reactor physics and was told that i was wrong. how do you respond to that? i told them i was under the impression it was how i stated, but instead of doubting what i was told i would research it out of interest. i'll never know if they were testing me or just dumb!
that should give you a real edge if your interview is anything like mine was. it was for operator by the way. good luck!
