Competency Based Interview Questions: How Answers Get Scored
Competency based interview questions grouped by competency, how panels score answers on a rubric, and how to map your stories to the job ad.
On this pageWhat are competency based interview questions?
Summary
Competency based interview questions ask for past examples that prove a named skill from the job ad, such as teamwork, problem solving or integrity. Every candidate gets the same questions, and a panel rates each answer against a scale with sample responses for each level. To score high, find the competencies in the posting, prepare one specific story for each, and say clearly what you did, how and what changed.
Competency based interview questions ask you to prove a named skill from the job ad with a real past example. Every candidate gets the same questions, and a panel scores each answer on a set scale. Prepare one solid story for each listed competency.
These interviews are standard in government, the public sector and many large employers. They reward preparation more than charm. Here are the quick answers.
Quick answers by situation
| Your situation | What to do | Example line |
|---|---|---|
| "Describe a time when..." | Real story, "I" not "we," result at the end, 60 to 120 seconds | "At the permit office, I cut processing time from 21 to 12 days." |
| "What would you do if..." | Give your steps, then a similar past example | "First, I would check the facts. I did that last year when..." |
| No work example fits | Use school, volunteer or side work | "In my volunteer role at the food bank, I..." |
| The panel asks "What did you do?" | Separate your part from the team's | "The team built the plan. My part was the budget." |
| Your mind goes blank | Ask for a moment, then pick your backup story | "Could I take a moment to choose the best example?" |
What are competency based interview questions?
Competency based interview questions are structured questions tied to named competencies, such as teamwork, oral communication or problem solving. Most ask about past behavior ("Describe a time when..."), and some pose a hypothetical situation. Interviewers ask everyone the same questions in the same order and rate every answer against the same scale.
The US Office of Personnel Management (OPM) defines a competency as a measurable pattern of knowledge, skills, abilities, behaviors and other characteristics1. It is what a person needs to do a job well. In plain terms, a competency is how you do the work, not just what you know.
OPM describes the structured interview as a method that measures job-related competencies2. It asks about past experiences or about how you would act in what-if situations. All responses are judged against the same rating scale and standards.
Past-behavior questions rest on one idea, which OPM's interviewer training states plainly:
the best predictor of future behavior on the job is past behavior under similar circumstances.

How it differs from a behavioral interview
Our list of behavioral interview questions covers the general "tell me about a time" format. A competency based interview adds two things:
- A fixed competency list. It comes from a study of the job, not the interviewer's taste.
- A scoring rubric. The panel must rate each answer against it.
| Typical behavioral interview | Competency based interview | |
|---|---|---|
| Questions | Chosen by the interviewer | Fixed, tied to listed competencies |
| Order | Flexible | Same for every candidate |
| Follow-up probes | Free | Often pre-set and limited |
| Scoring | Overall impression | Each answer rated on a set scale |
| Common in | Private sector, startups | Government, public sector, large employers |
Some panels mix in what-if prompts too. Those follow the logic in our guide to situational interview questions.
Why do employers use a competency based interview?
Employers use the competency based interview because structure predicts job performance better than most hiring tools. A 2022 meta-analysis by Sackett and colleagues ranked structured interviews first among common selection methods, with an average validity of .42. Structure also gives every candidate the same chance and makes decisions easier to defend.
The research case is strong. HumRRO summarizes a 2022 review by Sackett and colleagues in the Journal of Applied Psychology. In it, structured interviews had the highest mean validity, at .425.
Next came job knowledge tests at .40, empirically keyed biodata at .38, work samples at .33 and cognitive ability at .315.
Fairness and federal hiring
Government hiring adds a second reason: fairness. OPM notes that structured interviews give candidates equal opportunities to share details2. They also help assess everyone consistently.
In 2023, OPM's Federal Workforce Competency Initiative published 32 general competencies4 for skills-based hiring. The list includes Teamwork, Problem Solving, Flexibility, Integrity/Honesty and Oral Communication. Those names often appear word for word in federal job announcements.
How are competency interview answers scored?
Panels rate each answer on a proficiency scale, usually 3 to 7 levels, with labels such as unsatisfactory, satisfactory and superior. Experts write sample responses for each level in advance, and interviewers match your answer to the closest one. Detailed notes back up every rating, so specific actions and results score higher than general claims.
OPM's structured interview training says rating scales are usually between 3 and 7 levels3. At least three are labeled, such as unsatisfactory, satisfactory and superior.
Experts write example answers for each level. Interviewers then match your response to the closest one.
The UK Civil Service works the same way. A Defra recruitment blog explains that candidates are scored on a scale of 1 to 7, and need at least a 4 on each assessment6 to progress. Note "each." A great teamwork story will not rescue a weak integrity answer.
What the panel writes down
Interviewers also take detailed notes that must be strong enough to justify the rating. OPM tells them to probe when a candidate says "we did" or stays vague. So the panel is listening for your own actions, in your own words.
Here is what a rubric for one competency might look like. This is an illustrative example, not an official scale.
| Level | What the answer shows (Teamwork, example) |
|---|---|
| Superior | Specific situation, own actions clearly separated from the team, conflict or obstacle handled, measurable result, lesson applied later |
| Satisfactory | Real example and own role described, result stated but general |
| Unsatisfactory | What-if or "we" answer, no clear personal action, no result |
Answer the sign, not just the question
Many job ads list behavioral signs under each competency, such as "shares details" or "builds consensus." Name those actions in your story. The panel checks for them line by line, so saying them plainly makes the match easy.
What are common competency based interview questions?
Most competency based interview questions fall into a few groups: teamwork, leadership, problem solving, communication, adaptability, integrity and customer focus. Each group has a predictable set of prompts. Prepare one main story and one backup for each competency in the job ad. Then a follow-up never leaves you without an example.
Below are common prompts for each group. The competency names match OPM's general list where possible.
Teamwork and leadership
Teamwork
- Describe a time you worked with a team to reach a shared goal. What was your role?
- Tell me about a time a team member was not pulling their weight.
- Give an example of when you put the team's goal ahead of your own task.
Leadership
- Describe a time you led a project or group without formal authority.
- Tell me about a time you had to motivate people through a difficult period.
- Give an example of a decision you made that was unpopular.
Problem solving and communication
Problem solving and decision making
- Describe a complex problem you solved. How did you gather details?
- Tell me about a time you had to decide with incomplete data.
- Give an example of a process you improved.
Oral and written communication
- Describe a time you explained a complicated topic to a non-expert.
- Tell me about a time you had to deliver bad news.
- Give an example of a document or report you wrote that changed a decision.
Flexibility, integrity and conflict
Flexibility and resilience
- Describe a time your priorities changed suddenly.
- Tell me about a setback and how you recovered.
Integrity and honesty
- Describe a time you were asked to do something you felt was wrong.
- Tell me about a time you admitted an error to your manager or a client.
Interpersonal skills and conflict management
- OPM's own sample prompt: describe a situation in which you dealt with individuals who were difficult, hostile or distressed3.
- Tell me about a disagreement with a coworker and how you resolved it.
For conflict prompts, our walkthrough of a conflict with a coworker shows how to stay fair to the other person.
How do you map your stories to the job ad competencies?
Pull every competency and behavioral indicator from the job ad. Then list your best work stories and match each one to one or two competencies. Fill gaps with school, volunteer or side-project examples. Finally, turn each story into a 60 to 120 second STAR answer with the competency, your actions and a result.
This step is where most candidates win or lose. OPM notes that structured interviews usually assess 4-6 skills3, so plan for 8 to 12 stories. Follow four moves:
- Extract Highlight every competency, skill and verb in the posting. In federal announcements, check the "Qualifications" and "How you will be evaluated" sections.
- Inventory Write down 8 to 10 work stories: projects, fixes, conflicts, wins and mistakes.
- Match Build a simple grid with skills across the top and stories down the side. Give each competency at least two stories.
- Shape Turn each story into a STAR answer. Spend most of the time on your actions.
Our guide to finding keywords in a job description shows a fast way to do the first step. For the last one, see the STAR method guide.
A good story often covers two skills, but lead with the one the question asks about. Also, keep the wording the same as on your resume, so your stories back up what the panel already read.
A fill-in-the-blank answer frame
Drop any story into this frame and say it out loud. It keeps you on "I" and forces a result.
"At [employer], [problem and why it mattered].
I [action 1] and [action 2], because [reason].
As a result, [measurable outcome]. That is how I approach [competency]."
What does a high-scoring competency answer sound like?
A high-scoring answer names a real situation and uses "I" for your actions. It explains why you chose them and ends with a measurable result or clear outcome. Low-scoring answers stay general, describe what the team did or say what you would do. The difference is evidence the panel can write down.
Compare two answers to the same prompt: "Describe a time you solved a difficult problem at work."
"I'm a natural problem solver. Whenever something goes wrong, we get together as a team and brainstorm until we find a solution.
I think it's really important to stay calm and look at all the options. I'd say that's one of my strengths."
The panel has nothing to rate here. There is no situation, no personal action and no result.
"At the county permit office, applications took 21 days to process and complaints were rising. I pulled three months of tracking data. I found that 40% of files were stalled, waiting for one missing form.
I drafted a one-page checklist for applicants, got my supervisor's sign-off and added it to the online portal. I also set up a weekly report of incomplete files, so we could call applicants early.
Within two months, average processing time dropped to 12 days, and complaints fell by about half."
Every sentence gives the panel something to note. Use real numbers from your own work, and never invent them.
What to say when the panel probes
OPM tells interviewers to clarify your role when you say "we did" or "our group"3. Expect follow-ups like these:
- "What was your part?" Name one action that was yours alone.
- "What would you do differently?" Give one real change, then the lesson.
- "Can you give another example?" Switch to your backup story for the same competency.
- "What would you do if...?" List your first two steps, then link to a similar past case.
[You said "we" fixed the backlog. What did you do?]
"Fair question. I built the tracking sheet and called the 30 oldest cases myself.
The team handled new cases while I cleared the old ones."
[What would you do if a coworker kept missing shared deadlines?]
"First, I would talk to them privately and ask what is getting in the way.
I did that last spring with a colleague who was overloaded. We split the reports, and both deadlines held."
Practice matters, because a strong story still needs clear delivery. Rezoom's AI mock interview lets you rehearse competency prompts out loud.

What mistakes cost points in a competency based interview?
The costliest mistakes are saying what you would do instead of what you did, hiding behind "we," skipping the result and recycling one story for every competency. Also avoid ignoring the competency named in the question and rambling past two minutes. Do not treat the panel's silence as a cue to keep talking.
Do
- Use a real, specific example for every behavioral question.
- Say "I" when describing your own actions.
- End each answer with a result, ideally measurable.
- Mirror the competency and sign words from the job ad.
Don’t
- Answer a "describe a time" question with a what-if.
- Credit the whole team so your role disappears.
- Reuse the same story for three different skills.
- Expect the panel to probe for missing details.
Name the competency in your first sentence
Open with a signpost such as "A good example of my problem solving is..." The note-taker can then file your answer under the right competency at once. It also keeps you from drifting into a different skill halfway through.
Expect a quiet room
In many structured panels, interviewers take detailed notes3 and limit probes. Silence is not a bad sign, so finish cleanly and stop.

Frequently asked questions
What is the difference between competency based and behavioral interview questions?
Most competency based interview questions are behavioral, but they are tied to a fixed list of skills and scored on a rubric. A behavioral interview can be looser, with questions picked by the interviewer and judged on overall impression.
How many examples should I prepare for a competency based interview?
Prepare at least two stories for each competency in the job ad. For a typical posting with five or six skills, that means 8 to 12 stories, since some will cover two skills.
How long should each answer be?
Aim for about 60 to 120 seconds. That is long enough to cover the situation, your actions and the result without losing the panel.
Can I use examples from outside work?
Yes. Volunteer roles, school projects and side work all count, especially early in your career. The panel rates the behavior, not where it happened.
Are competency based interviews used in the private sector?
Yes. Government agencies use them most consistently, but many large employers use structured, competency based formats because they predict performance and are easier to defend.
