He should have used his relatively high intelligence to figure out how to hack the test so he scored within the range of what they were looking for in intelligence.
Maybe he wasn't aware that appearing too smart would bar him from consideration.
I know that I've run into more than one interview where I've been flat out told that the interviewer thought I'd find the job unchallenging. I suspect that interviewers often conduct an informal assessment of whether the person seems to be smarter than the average employee and reject candidates who seem either much more or less intelligent than the typical employee there. I've debated removing my Masters degree from my resume and modifying my speech patterns to see if that makes me appear more like the type of employee that gets hired faster, apparently.
