Assume you gave a general 'ability test', measuring both verbal communication and computational (basic math skills like addition, subtraction, division, multiplication), to a group of job applicants for multiple entry-level financial analyst positions. Also assume that because of severe hiring pressures to fill 8 positions within a 4-week period, you hired all of the applicants, regardless of their test scores. What kind of impact could predictively happen as a result of this hiring decision? What other measurement and/or reliability tests would you have recommended be given to applicants to test required skills like verbal communication and computational skills but also increase the accuracy of qualified hires in a short time span? Explain why.

In general, what type of information/data does a selection decision-maker need to collect in making staffing decisions? Why is this important and what are ways in which this information can be collected?
