Structured Interview vs. Unstructured Interview: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 10, 2023
A structured interview follows a consistent format with predetermined questions, while an unstructured interview is more open-ended and adaptable.
Key Differences
In the realm of hiring and research, the structured interview and unstructured interview methods are both valuable, albeit for different reasons. A structured interview adheres to a fixed set of questions, ensuring each candidate or subject is assessed in the same manner. Conversely, an unstructured interview offers more flexibility, allowing for impromptu questions based on the conversation flow.
During a structured interview, the interviewer has a specific agenda and checklist, with little deviation from the set script. This format ensures consistency and reduces biases, making comparisons easier. On the other hand, an unstructured interview can evolve naturally, resembling a casual conversation, and potentially uncovering deeper insights or personal nuances.
While structured interviews are systematic and can be scored quantitatively, they might miss out on spontaneous information or not delve into specific areas in depth. In contrast, unstructured interviews, although richer in detail and adaptability, may introduce interviewer biases and make objective comparisons challenging.
The choice between a structured interview and an unstructured interview often depends on the goal. If the aim is to maintain uniformity and collect comparable data, structured is preferred. If the objective is to explore in-depth and foster a relaxed environment where the interviewee might share more, unstructured becomes the go-to method.
Both the structured interview and unstructured interview techniques have their strengths and weaknesses. While structured can seem impersonal and rigid, it's valuable for its objectivity. While unstructured can appear inconsistent, it's cherished for its depth and adaptability.
