Personal interviewing (face-to-face interviews) is the most widely used method of collecting data among quantitative types of research. The interviewer interacts directly with the respondent, asking questions according to a formalized questionnaire.

Professional organization of the field stage, selection of polling locations and competent quota design allows avoiding systematic bias, so the results can be extrapolated upon the general population.
Personal interviews are usually conducted in places where there is a large gathering of people or where the target audience of your company is. To ensure high quality of collected data, the use of questionnaires with a duration of more than 20 questions is not recommended (respondents are in a hurry, attention is dissipated, etc.).
Quality is guaranteed:
- For paper-based surveys (PAPI): by telephone control (audio recordings are provided to the customer);
- For tablet-based surveys (CAPI): by audio recordings of each interview + geolocation;
- Interviewers have work experience above 1 year;
- Compliance with ICC / ESOMAR Code.
