If you get invited to the open house.Congrats! DO NOT BE LATE! Make sure what ever you put on your resume adds up and you can back it up if they ever question it.
Do your best to pass the cognitive test. its not a matter if you finish the test or not. more like how many correct answers you get in the time given and how you follow charts.
If you pass the test and get to the interview. think safety first and customer service in most situations.
wait, wait, wait, wait... it sucks but at least they didn't say you're out.
If you get invited for the S&D overview... DO NOT BE LATE and dress to impress. listen to the instructors, take notes. ask questions if you have to (i usually say there are no stupid questions. then i started working trains. LOL. then customer service experience kicks in)
STUDY, STUDY, STUDY... its doable as long as you put in the time and really depends on how you want the job.
If you are currently employed do not resigned. study on you own time or take a leave if you have to. i was working, going to school and studying for S&D when i did it not to mention still accomplishing my responsibilities to my wife and kid.
If you pass the S&D and get to the panel interview... again think safety first and customer service.
wait, wait, wait, wait... hey at least you're still in it.
Good Luck to all... it will be all worth it in the end.
disclaimer: this is how the process was when i started a little over 5 years now.
