The question below consists of a set of labelled sentences. Out of the four given options, select the most logical order of the sentences to form a coherent paragraph.

P- Even though interviews are the most widely used employment technique, research has not been able to show that it has high predictive validity.

Q- An interview does not accurately assess the candidate’s ability at work, relevant experience and work skills.

R- A further problem with interviews is that factors that are not related to the job influence the employment decision: clothing, colour, ethnic origin, gender, accent, physical features or a disability might be such factors.

S- There is also evidence that interviewers make decisions very rapidly on little information and hence interviews are exposed to interviewer bias and failure of human judgement.
