A typical "crappy senior dev": Able to talk for hours about design patterns, but not able to print the sum of four integers when given thirty minutes, an editor, and a compiler for their favorite language. A "senior dev" whose qualifications are only recommending Cisco hardware (for others to manage) and HP blade servers (for others to manage) is not what I'm looking for.
