Do the interview. I currently work for Corporate Flight Management on a different airframe/contract. In my interview, the explained that if our contract tanked, they would try to find me work elsewhere in the company before just cutting me loose. I love this company. The CP and DO are great guys. The new executive management has done great things which are really stabilizing the company.
As for the experience, it's good two pilot crew experience on a scheduled route like you will see the rest of your career based on the goals you stated in the OP. If you have specific questions, PM me and I will answer what I know.
