Most important aptitude questions

 

An aptitude test is a systematic means of testing a job candidate's abilities to perform 

specific tasks and react to a range of different situations.

The tests each have a standardised method of administration and scoring.

The results are quantified and compared with all other test takers.

No prior knowledge is needed, as the tests measure innate ability at a particular competency.
