Final answer:
The multiple hurdle approach is best utilized when predictors are expensive because it arranges selection stages or hurdles sequentially to minimize costs. This method is not ideal for small businesses or when training is minimal, nor does it align with the compensatory approach.
Step-by-step explanation:
The multiple hurdle approach in the selection process is best used when predictors are expensive. This approach involves having several stages or hurdles, where the candidate must successfully pass one hurdle before moving to the next. This is effective when employers wish to minimize the cost of selection by first applying less expensive methods (like application forms or simple tests) before proceeding to more costly methods like personalized interviews or assessment centers.
Meanwhile, the compensatory approach allows for a candidate's higher score in one area to compensate for a lower score in another, which is not consistent with the multiple hurdle approach. The multiple hurdle model is less suitable for small businesses due to its complexity and cost implications and is not specifically related to the amount of training provided to new hires or whether it falls in the first half of the selection process.
