The face-to-face interview is one of the key methods of quantitative data collection. Its main advantage lies in the possibility it allows for intricate questions to be asked and interviews can also be augmented with visual materials (packaging, video spots, etc.). ACT interviewers are trained to hold face-to-face interviews in a variety of environments, including:

• At the respondent’s home
• Workplace
• In the street
• At the sales point
• Crowded place
