Well, several things occur to me.
The job might actually pay good money. But, if not, then maybe you don't understand just how tight the job market is right now. In other words, there are a lot of furloughed airline pilots these days, which forces folks to move back down "the food chain," and ratchets up the hiring mins in all sorts of what some people might refer to as "entry level jobs.''
Frankly though, operating an Aerostar isn't something I'd want to see an inexperienced person try to do, especially if (as I suspect) it's a night freight operation.
The key information I'd look for would be whether the operator short a lot of pilots; that is, does he have trouble keeping enough pilots on the property to keep his planes in the air. If so, it's probably low pay combined with poor operating practices, a combination that attracts the minimally qualified but keeps them around only until they can find something better.
There is a third possibility: He took a look at you and didn't like what he saw, so he reeled out some qualifications he knew you didn't meet, in order to get rid of you. Nothing personal and no offense intended; just trying to answer your question.
Best to you.
