This makes a lot of sense. I never understood what vague questions such as "What is your greatest strength?" or "What is your big weakness?" revealed anything about a person. Every candidate has a canned answer for these questions which revealed close to nothing about him or her.
An even better way to hire a person would be to rely on the opinion of someone who already knows the person and to examine the past work of the candidate. Huffcutt argues that job interviews should be used to sell the job to the chosen candidate, not to judge the candidate. It makes a lot of sense.
