My opinion is that you just have to get hired and go from there. You will have to do what ever is required and hope for the best. I have always been good with my hands and great welding skills. So I apply for a fleet maintenance position , but they need good engineers to produce timber sales. They say no one needs fleet maintenance, but timber sales yes. I tell them my college was related to mechanical engineering not civil engineering. They tell me good enough. They provided some wonderful things in a beautiful place free of charge near a town that hated the USFS personnel. So much so a fellow was murdered in a tavern and none of the locals would say a word thus no convictions. I work with some resource people now and they all have degrees, but can not see them leaping ahead real fast. It sounds like you have already made commitments so just jump in and see what you can accomplish as hard workers do get noticed. Unless you are a minority. I was asked to be part of a FF team and I said sure. Soon I had experience on a hot shot crew and heli tack crew. I used my knowledge setting up pumping stations planning various issues related to FF. Thanks
