Relying on one or two assessment methods, such as resumes and interviews, can limit your ability to gauge the quality of candidates and their potential performance. To get a more comprehensive and objective picture of their abilities, fit, and motivation, you should consider using multiple assessment methods. Pre-employment tests are standardized tests that measure various aspects of candidates' skills, knowledge, aptitude, personality, or behavior. They can help you screen candidates based on specific criteria. Work samples are tasks or projects that simulate the actual work that candidates will do in the role; they can help you evaluate candidates' skills, creativity, and quality of work in a realistic context. Additionally, references from previous employers, supervisors, colleagues, or clients can provide insights into candidates' work history, performance, achievements, strengths, and weaknesses. They can help you verify claims and identify any red flags or concerns.
