It is very hard to give you an estimate on your odds of getting into Corporate as a furloughed airline pilot.
Every company is different in who they will hire... For example, the company I work for would require that you resign your seniority number at your airline. They do this because they spend $35,000+ training a new hire and we don't want to be a "stopping ground" for "transients"...
There are probably some smaller operators out there who may bring you on to ride the right seat with some in house training...
Again, every company is different....
Good Luck!
