Little late to this one. But congrats on following your dreams! I really hope you get the position but if not, don't be discouraged. You mentioned that you would start volunteering if you weren't offered the position and that's great! Volunteering is definitely an excellent way to get some hands-on experience and also a bit of a way to get your foot in the door for the next time a position rolls around. Your background as a dispatcher is certainly a plus. Anyone that can operate calmly under stress would be an asset at a shelter.
Resources to look at for readying yourself and for your own education (and maybe areas in your field of interest!), anything by Dr. Sophia Yin. You can find her on YouTube. She was an amazing woman who liked to educate others on low-stress handling techniques for working with cats and dogs. She was a vet and an animal behavioral specialist, and a lot of what she taught is very useful in a shelter environment.
Reading up on things like cat and dog body language would be extremely helpful as well. My shelter created tons of playlists for training, practicing skills, and informational resources: https://www.youtube.com/user/willamettehumane/playlists. My advice for looking up training/informational videos on YouTube: be wary of anyone who doesn't promote fear free training.
As for more personal and introspective feedback: just preparing yourself for the reality of the position and of the field as a whole. As I'm not sure what the background of the shelter you're applying for is, I can't give you specifics but any rescue/shelter work comes with it's own unique stress and emotional challenges. Uncaring owners, abuse/neglect cases, sometimes hoarding situations, and sometimes euthanasia. Compassion fatigue and burnout are real issues and can hit those in the animal care field particularly hard. I'm lucky enough to work at a shelter with a high live release rate of our animals here. But the times that it doesn't work or the outcome is bad stick around. Even if there isn't anyone to "blame". Sometimes especially if there isn't anyone to "blame", no one to fault, and no reason other than it's a bad situation all the way around.
One particular instance hit me hard, especially since I was relatively new. There was no one to blame, nothing that could have been done to prevent it, but I wanted to be angry. I finished out my shift and went home.
Then I had an emotional freak out/break down. I seriously contemplated quitting that night.
Obviously, I didn't quit. But that was sort of a trial by fire moment for me, of "can I really handle this? Can I keep doing it if there are going to be other situations like this?" And I found that I can. There's still stuff that sucker punches me, moments where I have to tap out and take a break, but that's okay. No one here expects anyone else to be super human, to hold all the emotional impact in.
I'm absolutely not trying to scare you off or portray the field of shelter work as this emotional nightmare because it's really truly not. It hurts sometimes and it's supposed to; the numb sensation of "this doesn't bother me, I can handle anything" is actually pretty unhealthy. Knowing how to handle the hard stuff, feel it but not wallow in it, is the key. I love my job and the good outweighs the bad by far. I get to do good work with some pretty amazing people, many of whom have become really good friends of mine.
So my final advice, if you haven't found a good routine of de-stressing and decompressing, start now. Keep a journal, go for a walk at the end of every day, take up a hobby that has nothing to do with animal care, etc. And have fun!
