DOOR-TO-DOOR INTERVIEWING
An area is assigned to our interviewers after being chosen either by the client or one of our project directors. The interviewers go door-to-door and randomly ask people to participate in the survey. Door-to-door interviews may be a one-time questionnaire or a product test that might require several follow-up visits. An incentive is usually offered to respondents, with the amount being dependent upon the complexity of the study.
