Just remember, nobody cares how you get your experience down the road. If I were to do it again I would not hesitate flying for pay if I could get the gig. Screw the FAA. They are only interested in protecting their own butts in the name of public safety. The NTSB recommendations are constantly blown off in favor of the airlines/aircraft manufactures to the detriment of pilots and the public. Don't let their BS rules hamsting your career progression. Just be safe and don't be stupid and get over your head.

You have to know how to answer the question on your oral but after that, just fly. By the way, questions about rest and pt.135 have no place on a commercial oral. If you are asked those kind of questions, answer that you will obey the FOM (Flight ops manual) of the operator and will learn the specifics of the type of operation when you get employed by an operator. The rules are widely varied and depend on many variables.
