for what it's worth, here is my take on your upcoming interview...
The DO and CP are actually really good guys. The company is in the midst of huge turmoil right now, and the constant change has everyone trying to figure out what the heck is coming next. People are on edge - from the top to the bottom. Profits are down and heads are rolling.
All this means diddly to you - you just want to earn a paycheck.
Do your best during your interview. Study up on the CFRs. Be slow, deliberate, and humble if they give you a flight eval. Heck, do that anyway.
Do demand at least 55K to start, more for a crappy remote location. You might not get another raise for years, and you will be pissed when you discover that one of your coworkers who got hired after you is making that much, so impress them with your stuff, and hold fast to your salary demand.
If they won't pay that right now, be extremely polite and professional and let them think about it (and you) for a few days. If a week or two goes by and you are panicking, you can always call back and renegotiate starting salary. They are paying for your license, period. You invested an assload of time and money to get it, so don't give it away! This is the voice of experience speaking, I hope you are listening.
Remember that the people you are interviewing with have to pay peanuts (because thats what the owners dictate), and then they (the interviewers) have to deal with the consequences (the monkeys that work there). There is no pay scale, no union, no guarantee that your job won't change for the worse at any moment. Having said that, it is a paycheck that hasn't as-of-yet bounced. The job is mostly determined by who's/what's at your base. If you get there, you won't fly with other pilots, you will fly with nurses and medics. Don't be afraid to ask them to help you. And for God's sake don't scare them. A med crew on your side at an EMS gig makes life livable. A med crew trying to run you off usually succeed.
But I ramble....
Good luck and safe flights.
