What Is A Psychometric Test?

Psychometrics or tossing a coin?

Selecting individuals by interview produces nothing more than almost chance results.

Interviews are an 80% poor predictor of performance on the job.

Interviews are costly, biased and tend to clone existing personality types, for good or ill

Using Tests
