Structured, Unstructured and Mixed Interviews

The Importance of Choosing an Interview Format

There are multiple types of interviews, but to maximize the effectiveness of the selection process, it is crucial to focus on the most common and efficient formats.

The choice of format (unstructured, structured or mixed) will determine the degree of comparability between candidates and the depth of information obtained.

Unstructured Interview: The Free Format

The unstructured interview is characterized by the lack of a script or a predefined set of questions.

Questions are formulated on the fly, as the conversation with the candidate unfolds.

While this format may seem more fluid or natural, it has a significant disadvantage for selection: lacking a common set of questions, it is very difficult to objectively compare one candidate's answers with those of another, or against the job profile.

Structured Interview: The Standardized Format

At the opposite extreme, the structured interview is based on a pre-formulated framework of questions that is consistently applied to all applicants.

This approach is more mechanical, but its great advantage is that it allows for a direct comparison of responses across candidates and against the profile requirements.

This type of interview is highly recommended for high-volume selection processes or for operational positions, where validation of specific technical knowledge is the main priority.

Mixed Interviewing: The Balance between Structure and Flexibility

The blended interview combines elements of both of the above formats. It starts with a set of basic (structured) guiding questions to ensure that key points are covered.

However, unlike the purely structured interview, it offers the interviewer the freedom to delve into specific topics or explore interesting responses that arise during the conversation, without following a rigid script.

This format of balancing consistency and depth is best suited for the evaluation of management positions and many professional roles.

Summary

Choosing an interview format is crucial to effectiveness. The unstructured interview is a free-form format, with no predefined script. Its disadvantage is that it makes it difficult to objectively compare candidates.

The structured interview applies identical questions to all applicants. Although it is more mechanical, it allows a direct comparison. It is highly recommended for operational positions or high-volume recruiting.

The mixed format is best suited for administrative positions. It combines basic guiding questions with the freedom to delve into specific topics, striking a balance between consistency and depth.
