Skills Gap:
A potential employee does not the required skills and experience for the position up for hire.
Translation:
An esoteric software program or process that was not widely adopted until about a year ago when some managers heard about it at an over priced industry convention.
The employee is expected to have 3 – 5 years of experience with the program or process that did not exist 2 years ago and the company will not train the potential new hire.
