At that time you will fill out your application (or verify that info), then take a reading comprehension test, a basic math test, and the "Hogan Personality" exam.
On the reading test, they want to be able to see that you can read and comprehend the safety rules, operating rules, and overall be able to comprehend future everyday material, etc. The key here is even if you don't finish all of the test, you get the ones that you answer correct!
On the math test, they want to see that you are able to do simple math in your head. Here again, they want to see that you are able to answer them correctly. Same situation as the reading test if you don't finish the math they want to see you get the ones that you answer correct.
The "Hogan Personality" exam forms a certain pattern on the answer sheet giving the examiner(s) a visual of your mental state and your overall personality traits, and how you would be able to handle the nature of the work at the railroad. But be reminded it is only a tool, but a good one if you ask me. As long as you answer them honestly, you should have no problems being there are no issues going on with you. If you pay close attention, you will notice that several questions will ask about the same thing. Also, the test may not be the exact test your neighbor takes or one from a previous class. They do rotate them around.
Anyway, good luck.... let us know how you fair out. I am a freight conductor (on furlough right now), and I like my job overall (though still miss a couple of little perks at Amtrak).
OBS gone freight...
