I second this. Almost all of my class had distinguished themselves in some manner. Whether they were a certificate chief pilot, regional chief pilot, simulator instructor, PC check airman, line check airman or IOE/OE captain - all did something above and beyond the regular line dog. This is an unwritten recommendation from your company and if you can qualify for these positions, go for it.

One piece of advice: Do NOT man a simulator or chief pilots seat until you have your 1000-1300 PIC TURB. You have the potential to get locked into those seats and not be able to get your time to eject when the hiring is looking better.
