The author of "the Cult of Personality," Anne Murphy Paul, brought to light certain inconsistencies of relying on these tests to determine a person's capability. Paul said that the accuracy of these tests is highly questionable as they are designed like a dream analysis or a daily horoscope.
One of tests that Paul cited in his book was Myer-Briggs Type indicator which stems from the one by Carl Jung, famous psychologist. He also said that since a person's personality changes constantly, it can not be a reliable indicator of one's abilities. It was also highlighted that in the test, all the questions are self-assessed, specific to how a person sees himself rather than how the society sees him.
In a recent report, "Validity and Reliability of Personality Assessments" published in Boundless, every single one of these tests were discussed with regards to their validity and reliability. It was then pointed out that not all the personality tests are considered valid as it depends on where you are planning to use the test. Some corporations rate the personality tests poorly, as a credibility metric. The companies, in their feedback, also mentioned that it often leads to hiring of wrong people.
One company that stopped using personality tests for recruitment process was Whole Foods. Previously their recruitment team depended on personality tests heavily and the people they hired as a result lacked appropriate skills required for food preparation. Now the use of personality tests during hiring is falling into disrepute and most companies have already decided to eliminate it from their recruitment process.
