So long as you don't have to sell your sole to the company store, probably a good move. There seems to be an air of mystery to this program. I keep hearing about it, but only through the grape vine, without details. Even without the details, any formalized program is a plus!
As far as Junior training and experience, like Hydrodave said, lots of climbing around and getting dirty. If that ain't the case, your in the wrong place! Most sites stick the juniors behind a desk for umteen years, then one day, they expect them to pick up the instruments and jump into the field with flawless results. Getting out in the field and doing the job with experienced techs is crucial! That was the way of the industry in the past, but economics errased that type of training.
The good, the bad and the ugly! You have to see them all to establish a future foot hold on your career. You will see and hear a lot of rumbling on a variety of issues, on different sites, companies and people on this website. Some true, some not! As a junior, I suggest you take whatever comes your way, you need that 4000 to 6000 hours to meet the ANSI qual's. Stay flexible, diversified and open to new ventures. Take the sure things and forget about the speculative offers. There are a ton of companies looking for people at this time and will be in the future!
