Answer:
Option C Interviews should focus on skills that can be measured in an interview better than on a test.
Explanation:
The reason is that the person's intelligence is though in problem solving skills but this can also be done by questioning the person in areas where they can better extract information out of the person rather than using tests and by noticing his reactions and problem solutions offered. This means that the tests though helps in finding the intelligent person but it doesn't helps much because the willingness, eager to do things done and a pro-activeness of the person is everything. And these skills comes out when the person speaks in front of a recruiter which analyzes his behavior, his beliefs about things and many other things which gets clear overtime. So the basic mistake here by the management was poor way of extraction of information out of candidates.
