The company I work for used a combination of MMPI, Wonderlic, and a few math/logic tests. I passed everything no problem, except the MMPI. I was told to call the psychologist they used at the time and he explained to me that because I answered "perfectly" to the drinking issues section, the test assumed I was lying, and as such degraded my credibility enough to fail the test. He suggested that when I retake it (which they let me do), I pretend that I drink some, and answer the questions as such. I did and the spike in the "validity" scale went away. The actual scale in question is the "L" (lying) scale. It tends to inflate when you answer all questions of a certain type the same way. I don't have a link or anything, although I did read an article in NEJM a year ago that talked about one of the reasons for moving from the MMPI-2 to the MMPI-3 was a need to normalize some of the deviation scales that were using 1950s data.
