Believe it or not, NOT knowing anything about RRing is best when going for an interview. If you try and show you know some about the job, you won't be choosen, guaranteed. The interview will most likley include the local trainmaster along with an HR person, and as soon as that trainmaster believe's you think your know something about RRing, he'll pass you up. They DO NOT want people who think they know about RRing. In fact, even if you have experience in some cases, it's best if you not mention it. Almost every freight RR (accept CN and CP) prefer's to hire "freshmeat" as opposed to guys with experience. Seems they believe it's easier to mold them to their standards and make's them better train crew's. Personally I disagree, however that's the reality. I know for a fact at my terminal if you mention any knowledge regarding RRing at the interview, my Super won't give you a chance. He stated this boldly and loudly today in a meeting of trainee's. DO NOT MENTION YOU LIKE TRAINS OR IT'S YOUR LIFE'S DREAM TO BE A CONDUCTOR.
Now as far as being prepared to answer questions or know what they are looking for, knock yourself out. I spent several months researching what the RR's were looking for in an applicant, how to make my resume standout, and how to respond to the interviewer's questions, if and when I received an offer to their recruitment session. It payed off for me as I was invited and hired on my first two applications with NS and CSX. A little preparation can payoff in a big way. Just make sure you use this time to learn about "how to get hired", and NOT "how to do the job".
If your looking for a basic book on what the RR's are looking for and some tips to get hired on, look into "How to Get a RR Job". Do a search and you'll find the website and the book being sold under the same name. It's a good basic reference to get started with. Good Luck !!!! Drew g
