Along with pure ad-hoc interviews, we also regularly offer multi-topic interviews (MET).This form of survey represents an economical solution in which companies can ask a limited number of questions. Interviews are conducted face-to-face at the home of the interviewee. These so-called multi-topic interviews are known by the vivid name of "Omnibus" and allow several clients to ask questions on different subjects, in other words to share the same platform, hence their relatively low cost.
