Steve I feel your pain but at least you got the courtesy of hearing back from them.
In the IT industry in Charlotte they do not even confirm if they got your resume unless you get called in for an interview. I once did an 8 hour round robin style interview with no break even for the rest room only to not get a return call. The only way you hear anything at all no matter who the company is if you make it to the next level, otherwise they leave you guessing.
