Yes, as selection is choosing from among the candidates the ones, who best meet a position's requirements and eliminating the ones who are not suitable. To achieve this target, candidates are required to take a series of tests and interviews in different stages.
At each stage, many candidates are eliminated and only a few candidates move to the next stage. The process of elimination continues till the right ones are finalised. The above scenario clearly establishes the fact that selection is the process, through which unsuitable candidates are rejected and suitable ones are chosen. Therefore, it is regarded as a negative process.
