Not choosing or picking out specific things; treating all items the same without preference.
The nonselective approach to hiring means that anyone can apply for the job, regardless of their background.
Nonselective → It is formed from "non-" (meaning not) and "selective" (from Latin "selectivus", meaning choosing or picking out). The word "nonselective" means not choosing or picking out, indicating a lack of discrimination in selection.
Think of 'not' ('non-') choosing or 'picking out' ('selective') — that's why nonselective means not making a choice.
