Before you start
This page is one step of the behavioral interview guide.
Why interviewers ask this
Candidates ask this question because the number of stories decides what happens when a behavioral question arrives. The U.S. Office of Personnel Management (OPM) says behavioral description questions ask applicants to describe a past behavior in a situation relevant to the competency of interest. MIT's career office describes the purpose as measuring past behaviors as a predictor of future results. The interviewer cannot be satisfied by a general opinion; a real episode is required.
With too few stories, you stretch one episode over every question, and the interviewer hears the same project three times. With too many, you cannot recall the details of any. A weak candidate improvises and rambles. A strong candidate has a small, practiced set of true stories and picks the best fit.
Story selection from first principles
- Flex story
- A flex story is a single real episode with enough substance, such as a project you led under pressure, that it can answer several different behavioral questions when you change which part you emphasize. Flex stories are what make a small story bank possible.
In plain words
Think of a toolbox. A good mechanic does not carry one tool for every bolt; a few multi-purpose tools cover most jobs. Your stories work the same way. One strong episode can answer a question about leadership, another about deadlines, and another about pushing back. The analogy breaks in one place: you can change which part of a story you stress, but you cannot change the facts. Every story must be true.
In one precise sentence, the right number of stories is the smallest set that gives each theme the job is likely to test at least one real story, and the important themes two.
Step 1: Gather raw episodes from your own work
Gather raw episodes from your own work. Start with your most memorable experiences and recall specific details. Amazon's own preparation pages tell candidates to think of memorable experiences in previous jobs and recall specifics, and to have examples showing risks taken, successes, failures and growth.
Input: your résumé, projects and school or volunteer work. Output: a longer list of candidate episodes, with a line on what you personally did in each. Keep the episodes where you drove a meaningful part, something real was at stake, and you can describe a concrete result.
Then read the job description. A competency is a skill or trait, such as handling conflict, that an employer has judged critical to success in the job, and OPM notes that structured questions are built from competencies found through job analysis. Your list of themes should come from the posting, not from a generic list.
Step 2: Tag each story with the questions it can answer
Tag each story with the competencies it can answer, instead of writing one answer per question. MIT's career office says to consider how each example may connect to one or more questions and to prepare to adapt on the fly. Its own example: a leadership story could also be adapted to communication skills, work ethic, and time management.
The same page warns that scripting or memorizing stories may limit your ability to adapt. So keep each story as a bullet outline, not a paragraph. Write the situation in a line, your actions in a few bullets, and the result. Use "I" for your own actions, as MIT advises, even when the project was a team effort.
Here is an illustrative bank of six stories, each tagged with two or three of eight competencies. That gives sixteen story-competency pairs, and seven of the eight competencies have at least two stories. Only conflict has a single story, which is a gap to fill.1
Text description of the diagram
- Seven of the eight competencies have at least two stories.
- Conflict has only one story, a gap to fill.
Step 3: Check coverage, then cut the rest
Check that every theme has a story and cut the rest. The arithmetic shows why the advice lands in a range. If each story can honestly cover three competencies, covering eight themes once needs three stories and covering each twice needs six. If each story covers only two, the same goals need four and eight stories.1 That is where "about six to eight" comes from: it is this page's synthesis of the arithmetic above, not a sourced fact.
| Competencies to cover | Themes per story | Depth | Stories needed |
|---|---|---|---|
| 8 (illustrative) | 3 | one story each | 3 |
| 8 (illustrative) | 3 | two stories each | 6 |
| 8 (illustrative) | 2 | two stories each | 8 |
| 16 principles | 3 | one story each | 6 |
| 16 principles | 2 | one story each | 8 |
| 16 principles | 3 | two stories each | 11 |
| 16 principles | 2 | two stories each | 16 |
The last four rows use the 16 Amazon principles; Amazon gives no story count, and the Amazon Leadership Principles page covers them. Amazon's loop page says five 55-minute interviews, with different interviewers assigned to different principle areas, and that each interviewer will typically ask two or three behavioral-based questions. That is about 10 to 15 questions in a loop, so a loop needs more breadth than a typical interview.1
Step-by-step description
- List real episodes from your own work.
- Mark the competencies each story can answer.
- Cover every theme, then drop the rest.
- Gather raw episodes from your own work.
- Tag each story with the competencies it can answer.
- Check that every theme has a story and cut the rest.
You now have the full method: gather, tag, check, cut. Last, time each story. MIT's guide suggests a split of Situation 20%, Task 10%, Action 60% and Result 10%, meant as a guide. For an illustrative two-minute answer, that is 24 seconds, 12 seconds, 72 seconds and 12 seconds.1
Knowing it is half the job. Saying it is the other half.

Start Free Trial →The Staff-level answer
How many stories do you prepare for behavioral questions?
I keep a small bank of about six to eight stories, all from my own projects. Each one is tagged with the competencies it can answer, so a conflict story can also answer influence. I check the job description and make sure each theme it stresses has one story, and the main ones have two. I don't memorize scripts. I keep bullet notes on the situation, my actions and the result, and shift the emphasis to fit the question. If nothing fits well, I use the closest story and say what I learned.
What makes it Staff-level: it names the method (tagging and coverage), the limit (no memorized scripts) and the fallback, rather than just giving a number.
The rubric
| Dimension | Weak answer | Strong answer | Staff answer |
|---|---|---|---|
| Count | Gives one number as a rule | Gives a range and a reason | Ties the range to coverage of the job's themes |
| Coverage | Same story for every question | One story per theme | Two for key themes; gaps found in advance |
| Adaptability | Recites a memorized script | Uses STAR notes | Reframes one story for several questions |
| Honesty | Embellishes or borrows | Uses true episodes | Uses true episodes with real stakes and results |
| Fallback | Freezes on a new question | Picks the closest story | Names the closest story and what it taught |
Three variants of this question
How many stories do I need for an Amazon interview?
Amazon states no number on its pages; its interview guide tells candidates to develop specific examples that show their experience with each Leadership Principle. With 16 principles and stories that each cover two or three, covering each principle once takes about six to eight stories; covering each twice takes eleven to sixteen.1
Can I repeat a story in the same interview?
Reuse one only when the question truly needs it, and change the angle: a project that answered a deadline question can later answer a conflict question through a different decision. Repeating the same facts in the same words signals a thin bank. A deeper bank lowers the odds of needing to.
How many stories do I need for a one-hour interview?
Plan for more questions than you expect. Amazon says each interviewer will typically ask two or three behavioral-based questions in a 55-minute interview, but other employers vary and give no figure. A bank sized for coverage of the themes, not for the expected question count, handles both a single deep probe and a rapid series.
Common mistakes
- "I wrote a full script for each story." (wrong) MIT warns that scripting may limit your ability to adapt. (right) "I keep bullet notes and tell it fresh each time."
- "We delivered the project." (wrong) The interviewer cannot tell what you did. (right) "I wrote the plan, and I resolved the dispute."
- "More is better, so I prepared as many as I could." (wrong) A bank too big to recall is not usable. (right) "I cut to a bank I can retell in detail."
- "All my stories come from one project." (wrong) A single project cannot show range. (right) "I draw on several projects, or on school or volunteer work."
- "Amazon requires a set number of stories." (wrong) Amazon's pages give no number. (right) "I prepare to the principles, not to a quota."
Follow-up questions
Is three stories enough?
Three is a floor, not a target. MIT's three to five works if time is short, and three stories cover eight themes once only if each story honestly covers three of them.1 About six to eight leaves second options. See the common interview questions page to test the bank.
How long should each story be?
Aim for a short, focused answer that spends most of its time on your actions. A two-minute answer with the MIT split is about a minute and twelve seconds on action. The guide to answering interview questions covers delivery.
What if I have little work experience?
Use school projects, volunteer work or part-time jobs, as long as you did something specific and can describe a result. The test is a true, concrete example, not a job title. Your opening answer for tell me about yourself can point to the same episodes.
Can one story answer a weakness question?
Yes, if the episode contains a real shortfall and what you changed afterward. Tag it for failure and growth, then adapt it to the greatest-weakness question.
- No official source sets a number; schools and coaches give ranges, and about six to eight is this page's synthesis of the coverage arithmetic.
- The right count is the smallest bank that gives each theme one story and the main ones two.
- Tag each story with the competencies it can answer, so one episode serves several questions.
- Keep bullet notes, not scripts, and use "I" for your own actions.
- Use the job description to choose the themes, and find gaps before the interview.
