Minnesota Multiphasic Personality Inventory, a 567-question T/F test that candidates take on Day 2 of the interview process. Immediately following the test you're then interviewed by a Psychologist who uses the results of the MMPI along with a simple bio sheet that you filled out the day prior to evaluate you. My shrink session took about 45 minutes or so, and included a lot of TMAAT questions, more so than during the panel interview on Day 1, which included more WWYD-type questions. Most folks make it through the MMPI without any issues, but a small number end up being flagged for a Psych Review Board. That said, I'm not aware of too many folks not ultimately being cleared by the Psych Board. 1 of 4 in my interview group was flagged, but he was cleared and we'll all be starting Indoc soon.
