Barrier:
Companies are isolating themselves from talent with common practices

The more companies try to achieve efficiencies thru hiring tests, forms & parameters the more they also narrow and isolate themselves from potential candidates.   Partly due to federal & state requirements to produce ever tightning standardized practices, hiring parameters narrow.  Partly due to the demand for additional black on the bottom line.   Any time a methodology narrows it also begins to isolate itself.  Standardization & uniformity should be achieved thru less conformation, a more open environment & with methods that widens parameters, but not lowering standards.  With current technology and economic climate hiring standards are ripe for a positive change. EXAMPLE: Companies are looking at new methods ( including poplular social media) to attract the coming of age work force, BUT are still using the same looking glas to categorize, evaluate, test its new found resource.  Another concern is a large number of professionals are needing to change industries & narrow parameters will eliminate good transitional talent.
