    When recruiting employees, firms typically use two types of interviews: structured and unstructured interviews. Each one, like job candidates, has its own set of strengths and shortcomings. However, do the benefits of a structured interview outweigh those of an unstructured interview?

You want one that can assist you in swiftly finding the proper prospects so that you can get the right individual on the job to help your company flourish. While organized interviews are commonly used in quantitative research, unstructured interviews are widely utilized in qualitative data collection since they focus on describing the study subjects.

    What is a Structured Interview?

    The most systematic sort of interview is the structured interview. Unlike in unstructured interviews, the interviewer uses predefined questions in a predetermined order.

    Structured interviews are frequently one-sided. They can be either multiple-choice or dichotomous, which implies that participants must select one of two options for each question. Although open-ended structured interviews exist, they are uncommon.

    You may compare responses between participants in a uniform context by asking a set of questions in a predetermined order. This can assist you in identifying trends and highlighting areas for additional research, and it can be a beneficial explanatory or exploratory research tool.

    Have you heard of structured interviews for hiring? They’re a great way to assess candidates fairly and objectively. Here is a helpful resource on how to conduct them effectively.

    What is an Unstructured Interview?

    An unstructured interview is the most adaptable since it allows for spontaneity. Unlike in a structured interview, the questions and the order in which they are presented are not predetermined. Instead, the interview moves forward based on the participant’s past responses.

    Unstructured interviews are free-form. This lack of organization can assist you in gathering detailed information on your issue while also allowing you to notice trends during the analysis stage.

    Difference between Structured and Unstructured Interviews

    As mentioned above, the fundamental difference between structured and unstructured interviews is that one has all of the questions prepared ahead of time, but the other does not follow any specific framework or type of questions. Here are the ten differences between structured vs unstructured interviews.

    Comparison Factor

    Structured Interviews

    Unstructured Interviews

    Nature

    These interviews are directive in character, meaning a sequential approach with correct parameters is followed. The method of leading questions with favored replies remains prominent. These are primarily facilitated discussions.This type of interview is non-directive, meaning the interviewer is not required to follow any predetermined pattern or leads. He or she must, however, take a non-judgmental stance and seek no preferred response. Active listening is still an essential tool for starting descriptive dialogues. This is more of an exploratory interview.

    Sequence

    The interviewer must follow a defined interview sequence with questions established in a specific order during a structured interview. Typically, one does not deviate from the established pattern.The interviewer is permitted to ask whatever questions during an unstructured interview. He or she may prepare a few questions beforehand but is not required to follow any interview sequence. It relies on the chance to turn the interview into a dialogue.

    Data Collection

    A systematic interview yields quantitative information. While this data is measurable, it lacks specifics about the candidate’s behavior in a particular setting or occurrence. Furthermore, candidates cannot be discovered outside of the format.In qualitative research, an unstructured interview is utilized to obtain data. Because the candidate can use descriptive language, the interviewer can get detailed information and better understand a person’s situational comprehension.

    Types of questions

    Close-ended questions are used in this type of interview, allowing the interviewer to limit the available responses to pre-conceived possibilities. Compared to unstructured interviews, the validity of the data recorded is significantly lower.This interview contains open-ended questions that allow the candidate to explore many points of view. Furthermore, modifying the research questions enables the interviewer to acquire a better understanding. These interviews have greater legitimacy because the interviewer obtains detailed information about the discussed issue.

    Example of questions

    In a structured interview, all candidates are asked the same questions, such as:
    • Tell us about yourself.
    • What are your strong points and weak points?
    • What do you know about our business?
    • Why should we employ you?

    Such questions encourage a regulated and uniform response, simplifying comparison and minimizing the impact of personal bias.

    The questions in an unstructured interview vary from candidate to candidate and follow a conversational pattern, such as
    • Do you enjoy utilizing our product/service?
    • What changes do you think we can make?
    • What are your thoughts on industry trends regarding our product/service?
    • Why do you prefer or use our product?

    Such questions are susceptible to interpretation and spark more significant debate.

    Time Duration

    Structured interviews can be completed in less time if a pre-planned set of questions is in place. When appealing to a bigger pool of candidates, it is most effective.Unstructured interviews become time-consuming when there is no predetermined questionnaire in place. The longer the interview, the deeper the conversation.

    Research

    Structured interviews are a type of descriptive research that involves the systematic collection of data. In addition to being cost-effective, these interviews can yield results quickly.Unstructured interviews are descriptive research methods typically used to examine a small data sample. These interviews are tailored and require experienced interviewers, which is both costly and time-consuming.

    Tools surveys

    Surveys and questionnaires are used to collect helpful information during structured interviews. Such tools make data administration and comparison easier. A structured interview can also occur physically or online, using predetermined formats and methodologies.An unstructured interview uses audio recorders, camcorders, and cell phones. Furthermore, these interviews require a personal connection between the interviewer and the interviewee to obtain accurate information.

    Comparability

    The information gathered during a structured interview is compared. The collective data samples are all subjected to identical investigation conditions, making them perfect for quantitative observation and analysis.Data samples cannot be compared because an unstructured interview is more likely to differ for each participant. The interviewer is instructed to inquire about the candidate’s details, spontaneity, and situational awareness to make the final decision.
    UsagePositivists, who emphasize a quantitative nature, employ data acquired through structured interviews to provide statistics. A positivist approach can be rigid but creates sound decisions based on logic and scientific understanding.Data from unstructured interviews are used by interpretivists, who prefer qualitative data and draw conclusions only after thoroughly analyzing all social actions. An interpretive argues that human behavior is complex and cannot be measured by social activities or quantitative measures.

    Structured vs Unstructured Interviews: Choosing the Right Approach for Hiring

    The difference between structured and unstructured interviews lies in the questions asked. Structured, more formal, and consistent interviews are expected in mass hiring, such as university internships.

    Unstructured interviews, on the other hand, are best suited for assessing candidates who are being hired for specific roles. They allow for more creative exploration, are more adaptable, and encourage a more accessible flow of discussion.
