Do positions such as check pilot and instructor get you more pay?

How does working a day off work in terms of pay and bidding?

If you come in as a Be99 captain, do you get ATP before advancing to the 1900 and are there any training contracts with that?

Since its an out and back route, would I be sitting in the hotel room most of the day between flights or does that change per route?

Are all pilots scheduled a 5 day with the ability to work a day more or how does that start off? This would be for a Be99 in DFW as the beginning.

Thanks!
