What does an interviewer do?

An interviewer conducts interviews of a prescribed nature either in person or on the phone. Personal interviews tend to be held in neighbouring town centres (eg. In a shopping centre or high street shop) as opposed to phone interviews which are usually conducted at home. concertare issues training to all its interviewers to ensure that all the same key criteria are covered, including questions and behaviour guidelines for the duration of the interview. To avoid unnecessary variation between interviewers, each of these guidelines must be followed in the test itself. Because of this, the mystery research is regularly monitored by concertare and its clients.
