Carry on!
Fantastic!! Tons of good juju!!!!!So....
The second interview resulted in me getting the facility grand tour by the General Manager, embarrassing the guy who performed the CAD test, and being told it's a good thing I've made it this far.
My insider said they are impressed and have nothing but good things to say about me. I must have REALLY snowed them.
Hopefully an offer will result by next week thus ending my 1.5 year long search.
