In the book "Precious and Grace" by Alexander McCall Smith, the main character reflects on the challenges faced by employers when selecting candidates from a large pool of applicants. She is intrigued by the sheer number of individuals vying for jobs and questions how employers can effectively narrow down their choices.

Her contemplation leads her to consider whether all applicants are given an interview opportunity, and if so, how one can differentiate among them when many possess similar qualifications. This thought process highlights the complexities of the job selection process in a competitive job market.
