I’ll echo the response of antarctic cat. If you didn’t go to the job fair and you don’t get hired you might consider going next year. The only really great reason to go is to get names of people to keep in touch with. If you are really lucky, when you do call back the person actually remembers you. Without the personal contact you are at a distinct disadvantage, but not a hopeless one.
I would call RPSC and take your chances that someone might put you in touch with the right person. Be prepared that right now most of the positions will have been given out for the upcoming season. That said also be prepared that a fair number of the first picks will either back out at the last minute or flunk the physical. That will be your best “in” ,to be patient and be ready to go in an instant. If you do get the call to be an alternate then be proactive and get all the medical done as fast as possible. If the first choice person doesn’t get their medical done by the deadline, you will probably have an opportunity to slide into their spot. It’s all very difficult your first time in. Once here it’s a lot easier to be rehired for the next season.
