Some companies will run the same ad for a high-paying IT or engineering position just about forever, but for some reason every one who applies is turned down because they only have 26 of the 27 industry-and-corporate-specific skills this job requires. Then, lo and behold, when they are unable to find even one single "qualified" American applicant, in comes the H1-B hire from Shanghai or Mumbai, who "just happens" to have all 27 of the 27 industry-and-corporate-specific skills and just the right number of years of experience!
It's absofreakinlutely amazing!
