There isn't the same level of info out there regarding mil-to-corporate because, frankly, not that many mil guys/gals are interested (everyone going to the airlines), and it's a smaller pond in the first place.

Part 91 operations tend to be much more of a "who you know" group as far as hiring. Part 135 operators, the bigger ones at least, have a more airline-like hiring process, and often starting at one of the 135 operations can open doors in the Part 91 world as you meet people and learn about other operations out there.

I was always a "pilot shortage" sceptic. But it's happening. Corporate, in some markets, is being decimated and the huge vacuum that is the airline industry is just getting started. There are opportunities. But beware: in my estimation there are 10% of corporate operations that are like winning the lottery (good pay and bennies, great people and manageable schedule), about 20% that are pretty good, but some aspect or another (pay, schedule, 401k) is lacking, and the remaining 70% are $hit. Hopefully these 70%ers feel the pain of the pilot shortage and either up their game or go the way of the Dodo.

Good luck in your post-mil job search.
