The Complete Guide to Interview Methodologies
An interview methodology is the framework a hiring team uses to plan, run, and score a job interview: what questions get asked, how much structure the conversation follows, who conducts it, and how answers are compared across candidates. The methodology you pick decides two things that matter far more than the interviewer's personal instincts: how predictive the interview is of actual job performance, and how consistently your hiring decisions hold up when a different recruiter runs the next round.
This guide walks through every major interview methodology in use today, when each one earns its place in a hiring process, and how modern AI-led Round 1 interviews (like the ones Fabric runs) fit into the same framework. It is written for recruiters and talent leaders at enterprises hiring in bulk, and at IT services and staffing firms with limited submission shots per role, where picking the wrong methodology at Round 1 wastes panel time or costs you the candidate.
If you want to see how a structured, AI-led Round 1 works in practice, you can walk through Fabric's interviewer without booking anything.

What is an interview methodology?
An interview methodology is the underlying framework that shapes how a job interview is designed, conducted, and scored. It covers four decisions the hiring team has to make before the first candidate sits down: how much structure the conversation follows, what type of questions get asked, who is in the room, and how each answer is rated on a shared scale so candidates can be compared side by side.
Methodology is not the same as interview format. Format is what a candidate experiences (a phone screen, a panel, a live coding round). Methodology is the rules the interviewer follows underneath. Two panel interviews can use completely different methodologies, and that difference is usually what determines whether the panel actually agrees on the hire.
Picking a methodology matters because it drives predictive validity. Meta-analytic research summarised in SHRM's assessment methods guide finds that the format of the interview, not the seniority of the interviewer, is what most strongly predicts whether the hire will perform on the job.
The main types of job interviews at a glance
Most hiring teams end up using a mix of methodologies across rounds, rather than one format for the whole funnel. The comparison below is the shortest useful summary of the options covered in this guide, the buyer or recruiter pain each one solves, and where it tends to break.
| Methodology | Best for | Weakness |
|---|---|---|
| Structured | Comparability across many candidates for the same role | Feels rigid if the interviewer follows it too literally |
| Semi-structured | Deeper probing into reasoning, while keeping a shared spine | Slightly harder to compare across interviewers |
| Unstructured | Culture and chemistry conversations very late in the funnel | Lowest predictive validity of any format |
| Situational | Roles where future scenarios matter more than past ones | Rewards articulate candidates over experienced ones |
| Behavioral | Roles where past behavior is a strong signal (people leadership, sales) | Less useful for early-career candidates without a track record |
| Competency-based | Roles with a defined competency framework already in place | Only as good as the underlying competency model |
| Panel | Final rounds where multiple stakeholders need to weigh in | Expensive to schedule, easy to run without structure |
| Technical / case-based | Roles where the work sample is a live proxy for the job | Vulnerable to AI-assisted cheating without safeguards |
Structured interviews
A structured interview asks every candidate the same set of pre-defined questions, in the same order, and scores each answer against the same rubric. There is no adjusting for how well the conversation is flowing, no clever tangents, and no reordering. The whole point is that two candidates who sit for the same role can be compared directly, because the raw material of the interview is the same for both.
Research summarised by SHRM finds that structured interviews predict job performance roughly twice as accurately as unstructured ones. That is the single biggest reason structured formats have become the default for high-stakes and high-volume hiring: the gap in predictive validity is large enough that it outweighs most other design choices you might make.
Structured interviews are the strongest fit for bulk hiring, campus hiring, and any role where you will run Round 1 against many candidates. They are less useful for exec search or highly specialised roles where the value of the conversation comes from the follow-ups more than the initial answers.
Unstructured and semi-structured interviews
An unstructured interview is the classic free-form conversation: no fixed question list, no rubric, whatever comes up comes up. It is the format most people picture when they hear "job interview," and it is also the one modern hiring research most consistently advises against using as a primary signal. The reason is not that unstructured conversations are useless, but that they are dominated by interviewer bias and first-impression effects that have very little to do with the candidate's ability to do the job.
A semi-structured interview is the middle path. The interviewer works from a fixed core set of questions, but is allowed and expected to probe individual answers with follow-ups. It trades a small amount of comparability for a lot more depth in the answers you actually get. Semi-structured is a reasonable choice for Round 2 or Round 3 with a shortlisted candidate, where you already have a comparable Round 1 signal and now you want to understand how they think.
Situational and behavioral interviews
Situational and behavioral interviews are two closely related structured methodologies that differ in one important way: what tense the questions are in.
A situational interview asks the candidate what they *would do* in a hypothetical scenario relevant to the role. The scenarios are usually written from real problems the team has faced, and the rubric grades answers against the qualities of a good response, not a specific right answer. Situational works well for roles where the future problems will not look like the past ones, or where you are hiring early-career candidates who don't yet have a track record to draw on.
A behavioral interview asks the candidate to describe a specific past situation they actually handled. The idea is that past behavior in a comparable situation is the strongest available predictor of future behavior in the role. According to LinkedIn Talent Solutions research, behavioral questions are the format most hiring managers reach for when they want to assess soft skills like leadership, adaptability, and collaboration, because those qualities are hard to fake in a story about a real event.
Behavioral answers are often scored on a behaviorally anchored rating scale (BARS), which gives each rubric point a concrete anchor description so different interviewers grade the same answer the same way.
Competency-based and panel interviews
A competency-based interview is a structured interview built on top of a defined competency framework: a list of the specific skills and behaviors the role requires, with example indicators for each. The questions target one competency at a time and the rubric ties directly back to the framework. This methodology is popular in large enterprises that already have a competency library and want every interview to score against the same shared model.
A panel interview puts multiple interviewers (usually three to five) in the same conversation with a single candidate. It is a format rather than a methodology on its own, since a panel can run structured, semi-structured, or fully unstructured. What matters is whether the panel has agreed in advance on which competency each interviewer is scoring and on the shared rubric. Panels that skip that step tend to average out to no useful signal at all, and they cost the most panel hours to run. That is exactly the pain enterprise recruiters describe when Round 1 has already burned through the calendar.
Technical and case-based interviews
A technical interview puts the candidate in front of a live work sample: writing code, walking through system design, debugging a broken snippet, or doing a pair-programming session with the interviewer. A case-based interview does the same thing for non-engineering roles: a business case, a product teardown, a guesstimate, a cold-call or cold-email simulation for sales.
Both formats are extremely predictive when the work sample is a good proxy for the actual job, because you are watching the candidate do a version of the job you are hiring them for. The catch, over the last two years, has been AI-assisted cheating. Live coding rounds and take-home assignments are now visibly vulnerable to invisible interview assistants, and the industry has been scrambling for a response. Any modern technical interview methodology therefore needs to include a design decision about integrity alongside the question set itself.
How to choose the right interview methodology for hiring
There is no universal right answer, but there is a defensible way to pick. Work backwards from three questions:
- What is the round for? Round 1 is filter for basic fit and eligibility. Round 2 tests depth on the specific role. Later rounds test team fit and stakeholder alignment. The methodology should match the job of the round, not be the same for all of them.
- How many candidates will run through it? High-volume rounds (bulk hiring, campus, IT staffing pre-screens) need methodologies that are directly comparable across hundreds of candidates. Structured, situational, behavioral, and AI-led Round 1 formats all qualify. Unstructured does not.
- Is the evaluation objective or subjective? Engineering, sales, analytics, and most operational roles have relatively objective Round 1 signals (does the code compile, does the pitch land, is the analysis right). Design, content, and creative roles have a large subjective component that a rubric cannot fully capture.
A reasonable default for most Round 1s is a structured methodology, with situational or behavioral questions for the interpersonal component and a work-sample or technical section for the role-specific component. Move to semi-structured or panel formats only once the candidate has cleared Round 1.
Where AI-led Round 1 fits into modern interview methodology
An AI-led Round 1 interview is a structured methodology delivered by an AI agent instead of a human interviewer. Every candidate sees the same questions, in the same format, scored against the same rubric. That is what makes it a full methodology rather than a simple screening tool. The underlying framework is the classic structured interview, applied consistently at a scale that would be impossible to staff with human interviewers on the same day.
Fabric runs an AI-led Round 1 across both tech and non-tech roles, with formats tailored to what the role actually requires: pair programming and OpenRound for engineering, case studies and guesstimates for product and consulting, cold-call and cold-email simulations for sales and customer success, and prompting exercises for non-tech roles that need AI fluency. The methodology stays structured; the surface changes to match the work.
Fabric's Interview Engine screens, scores, and shortlists candidates. The recruiter or hiring panel still owns the final decision, which is the whole point of using a Round 1 methodology at all. Cheating detection is built into the interview as a core capability, not bolted on as an add-on. It is designed to flag AI-assisted answers and surface them to your recruiter as a signal to weigh, not as an automatic reject.
The honest limitation: an AI-led Round 1 is the strongest fit when the evaluation criteria for the role are objective (engineering, sales, marketing, most operational functions). For roles with genuinely subjective evaluation (visual design, long-form content), a human interview remains the better methodology.

FAQ
What is an interview methodology in hiring?
An interview methodology is the framework a hiring team uses to plan, run, and score a job interview, covering the question format, how much structure the conversation follows, and how answers are compared across candidates. It shapes fairness, predictive validity, and how repeatable your hiring decisions are.
What are the main types of job interviews?
The most common types are structured, semi-structured, unstructured, situational, behavioral, competency-based, panel, technical, and case-based interviews. Most companies use a mix across rounds rather than a single format.
What is a structured interview?
A structured interview asks every candidate the same set of pre-defined questions in the same order, with a shared scoring rubric. Meta-analytic research summarised by SHRM finds it predicts on-the-job performance roughly twice as accurately as an unstructured interview.
What is a semi-structured interview?
A semi-structured interview uses a fixed set of core questions but lets the interviewer probe answers with follow-ups. It trades a small amount of comparability for deeper insight into a candidate's reasoning.
What is an unstructured interview?
An unstructured interview is a free-form conversation with no fixed question set or rubric. It is the most familiar format and the least predictive of job performance, which is why most modern hiring guides advise against using it as the only signal.
Which interview methodology is best for high-volume or bulk hiring?
Structured or AI-led Round 1 interviews scale best, because both use the same questions and rubric for every candidate. That comparability is what keeps decisions consistent when you are running hundreds or thousands of interviews for the same role.
Are AI-led interviews a valid interview methodology?
AI-led interviews are a structured methodology in practice: every candidate faces the same questions, in the same format, scored against the same rubric. They work best for Round 1 on roles with objective evaluation criteria; subjective roles like design still benefit from a human interview.
