Conducting effective customer interviews requires careful preparation and a strategic approach. Prioritize face-to-face interactions, whether through video calls or in-person meetings, as they yield deeper insights than written surveys. Build rapport with interviewees to foster trust and encourage them to share unique insights. Delay introducing your ideas until the conclusion or avoid them entirely to prevent biasing responses. Focus on being a listener rather than a speaker; employ open-ended follow-up questions to facilitate rich discussions about their experiences and challenges. If recording is not possible, take detailed notes during the conversation to capture essential information for later analysis.
