Final answer:
The 'Ratios of offers made to acceptances' is an effective metric for gauging a company's ability to attract top talent in a competitive market, while 'voluntary employee turnover within 90 days' offers additional insight into the employment experience.
Step-by-step explanation:
To measure how effective a company is in hiring talent, particularly in a competitive market, one could use Ratios of offers made to acceptances. This metric would indicate the attractiveness of the company to prospective employees and reflect on the company's reputation, benefits, and compensation package relative to the competition. A high ratio suggests that the company is successful in convincing candidates that it is a great place to work. However, it is important to consider other metrics in conjunction with this to gain a full picture of hiring effectiveness; for example, voluntary employee turnover within 90 days can provide insight into whether the expectations set during the hiring process are met once the candidate begins working.
