Most guys think they are getting a jumpstart on their career by attending the mesa training program. Here is a few things worth considering.
1. You will get your 1st part 121 job quick no lie about that.
2. Then you will watch many former CFI's or Cargo dogs beat you to the left seat. By the time you have the necassary hrs in your logbook to upgrade to captain the CFI's and C-dogs (who have the same seniority) will be applying elsewhere with triple the amount of PIC on their RESUME. Remember PIC is everything, OK that and who you know.
3. With most of your experience coming from the right seat flying with an experienced captain. Be ready to learn what CFI'ing is all about once the newbies start coming thru enjoy.
