Which of the following is a common selection method used by employers?

• A. Interviews
• B. Aptitude and numerical tests
• C. References or background checks
• D. Job rotation

Answer: (A)

Selecting staff is about judging how a person will fit the job and the team, and interviews are a natural, direct way to do that. They let employers ask about past experiences, problem‑solving, and how a candidate would handle real work situations, plus they reveal communication style and motivation. Interviews can be structured to compare candidates fairly and can be used at different stages of the process, from initial screening to final decisions. While aptitude or numerical tests, references, and background checks are useful tools, they are often used to supplement interviews rather than replace them, and they don’t provide the same direct insight into how a candidate behaves and talks about their experiences. Job rotation is more about developing employees once hired, not a primary way to choose who to hire. So interviews remain the most common method used by employers.
