I once interviewed with an airline (for an "enterprise architect" position). I had every single "skillset" they asked for (including the nice-to-haves), did well in the phone screen, they brought me on site for a four hour face-to-face interview. Then they asked me to come back again for another four hour face-to-face interview (with different people). They never called me back.
