Essential Competency Interview (ECI): How to Prepare for a Police ECI

The Essential Competency Interview, commonly called the ECI, is an important stage in the hiring process used by a number of Canadian police services, particularly in Ontario.

You may see it described as an Essential Competency Interview, Essential Competencies Interview, police ECI or competency-based police interview. Although the terminology can vary, the purpose is generally the same: interviewers want evidence from your past behaviour showing that you possess the competencies and personal qualities required of a police officer.

This is not an interview you can prepare for by memorizing polished answers. You must identify authentic experiences from your life, organize them clearly and explain what you personally did, why you took those actions and what resulted.

If you are preparing for an upcoming ECI, anEDGE provides personalized police interview coaching with experienced former police officers, recruiters and interview specialists.

What Is an Essential Competency Interview?

An Essential Competency Interview is a structured, behavioural interview designed to assess whether an applicant can demonstrate specific policing competencies through examples from their past.

Instead of asking what you would do in a hypothetical situation, an essential competency interview question will generally ask you to describe something you have already experienced.

For example, you may be asked to discuss a time when you:

Adapted to an unexpected change
Built a productive relationship
Managed your emotions under pressure
Resolved a disagreement
Evaluated and improved your own performance
Worked effectively with people from different backgrounds
Made a difficult or ethical decision
Took responsibility for an error

These are representative competency areas, not actual questions from a particular police service. Every service establishes its own interview process, competencies, timelines and assessment standards.

For example, the Waterloo Regional Police Service ECI preparation page currently identifies flexibility, relationship building, self-control, self-assessment, and diversity and inclusivity as essential competencies. Waterloo also asks candidates to use examples from the preceding two years.

The Halton Regional Police Service recruitment process describes its ECI as a behavioural-style interview conducted by two recruiting officers.

Always follow the instructions provided by the police service to which you are applying. Interview formats and competency frameworks can change.

What Are Police Interviewers Looking for in an ECI?

The interview panel is not simply listening for an impressive story. Assessors are looking for specific behavioural evidence within your answer.

A strong response should demonstrate:

Your personal responsibility within the situation
The decisions you made
The reasons behind those decisions
How you communicated with the people involved
How you managed challenges or competing priorities
Whether your actions demonstrated sound judgment and integrity
The outcome of your actions
What you learned from the experience

Your example does not have to involve policing. Strong ECI examples can come from employment, education, volunteer work, community involvement, sports, military service or other meaningful life experiences.

The important question is not whether the story sounds dramatic. It is whether the example provides enough evidence for the panel to assess the targeted competency.

Essential Competency Interview Versus Local Focus Interview

The Essential Competency Interview and Local Focus Interview serve different purposes.

The ECI generally focuses on your past behaviour and how effectively you demonstrate required competencies. You will normally be expected to provide detailed examples of situations you personally experienced.

A Local Focus Interview may place more emphasis on:

Your reasons for choosing a particular police service
Your knowledge of the organization
Your understanding of the community
Local policing priorities and challenges
Your preparation for a policing career
How your values align with the police service

Some services combine competency, local-focus, suitability and behavioural questions into one interview, while others assess these areas separately.

Essential Competency Interview Questions: What Should You Expect?

Police essential competency interview questions usually ask for a specific example from your past. They often begin with phrases such as:

“Tell us about a time when…”
“Describe a situation in which…”
“Give us an example of…”
“Tell us about an occasion when you had to…”

A general question type might ask you to describe a time when you had to adapt your approach, address inappropriate conduct, overcome a setback, manage conflict or work with someone whose perspective differed from your own.

The precise wording matters. Listen carefully and determine:

What competency is being assessed?
What behaviour does the panel need you to demonstrate?
Which of your experiences provides the strongest evidence?
Does your example answer every part of the question?

Do not force a prepared story into a question that it does not properly answer. A well-rehearsed example can still receive a weak score if it fails to demonstrate the competency being assessed.

How to Select Strong ECI Examples

Selecting appropriate examples is one of the most important parts of essential competency interview preparation.

Choose a specific event

Avoid describing how you generally behave. The panel needs one clear situation with a beginning, a series of actions and an outcome.

Use recent examples

Some police services establish a specific recency requirement. Waterloo Regional Police, for example, currently requests situations from the past two years. Follow the timeframe given in your interview instructions.

Select examples with sufficient complexity

A routine interaction may not provide enough evidence. Look for experiences involving a meaningful challenge, responsibility, decision, conflict, risk or obstacle.

Make sure you played an active role

The assessors must be able to evaluate your behaviour. Choose examples in which you took meaningful action rather than simply observing what somebody else did.

Use authentic experiences

Never invent or exaggerate an example. Interviewers may ask detailed follow-up questions about your decisions, conversations, timing and results. Your answers must remain honest and consistent.

Prepare more than one example

One experience may demonstrate several competencies, but you should not depend on the same story for every question. Develop a varied bank of experiences covering teamwork, communication, judgment, adaptability, integrity, accountability, conflict and self-awareness.

How to Use the STAR Method in an Essential Competency Interview

The STAR method provides a useful structure for answering behavioural ECI questions:

Situation: What was happening?
Task: What were you responsible for?
Action: What did you personally do?
Result: What happened, and what did you learn?

Our complete police interview STAR method guide explains each part in greater detail.

Situation

Briefly provide the context the panel needs to understand the event. Explain where you were, what was happening and who was involved.

Do not spend several minutes giving unnecessary background information. The situation should set up the example, not dominate your answer.

Task

Explain your responsibility, objective or challenge. The panel should understand what you needed to accomplish and why it mattered.

Action

The Action is normally the most important and detailed part of an ECI response.

Explain:

What you personally did
What you said and how you communicated
What information you considered
What options were available
Why you selected your approach
How you handled resistance or obstacles
How you adjusted when circumstances changed
How you ensured your actions were fair, safe and appropriate

Use “I” when describing your contribution. You can acknowledge the team, but the assessors must be able to distinguish your behaviour from the actions of everybody else.

Result and reflection

Explain the outcome. Where possible, identify a clear or measurable result.

You should also discuss what you learned, what the experience taught you about yourself and whether you would do anything differently. Thoughtful reflection demonstrates maturity, accountability and self-awareness.

As a practical preparation guideline—not an official police scoring formula—keep the Situation and Task concise, devote most of your answer to the Action, and finish with a clear Result and reflection.

Why the Action Portion Is So Important

Many applicants spend too long setting up the story and then rush through their actions. This leaves the panel with insufficient evidence to evaluate the competency.

Saying, “I spoke with the person and resolved the problem,” is unlikely to provide enough detail.

The interviewers need to understand:

How you approached the person
What you said
How you listened and gathered information
What concerns or risks you identified
How you evaluated your options
Why you chose a particular course of action
How the other person responded
Whether you adjusted your approach
What you did to prevent the issue from recurring

Your actions reveal your judgment, communication skills, emotional control, integrity and problem-solving ability. This is where you demonstrate the competency rather than merely claiming that you possess it.

Common Essential Competency Interview Mistakes

Choosing an example that is too weak

The situation may technically relate to the question but lack enough responsibility, challenge or decision-making to demonstrate the competency effectively.

Using “we” throughout the answer

Police officers work in teams, but an ECI evaluates your individual behaviour. Clearly explain what you personally contributed.

Providing too much background

Lengthy explanations about the situation reduce the time available to describe the actions that are actually being assessed.

Failing to explain your reasoning

Do not only list what you did. Explain why you chose those actions and what information influenced your decisions.

Giving a memorized or scripted answer

Over-rehearsed responses can sound unnatural and may fall apart under follow-up questioning. Prepare the important details and structure rather than memorizing every sentence.

Missing part of the question

An ECI question may contain more than one requirement. Listen carefully and make sure your example addresses the entire question.

Omitting the result or lesson

A strong answer should show the outcome and what you learned. Reflection is especially important when the situation did not go perfectly.

Exaggerating the story

Experienced interviewers often identify inconsistencies. Your credibility and integrity are more important than making an ordinary experience sound dramatic.

How to Prepare for a Police Essential Competency Interview

1. Confirm the current interview format

Review the police service’s official recruitment information and your interview invitation. Do not assume that two police services use identical competencies or procedures.

2. Create a competency map

List the competencies being assessed and identify two possible experiences for each one.

3. Build a varied example bank

Use examples from different parts of your life. Include situations demonstrating leadership, teamwork, adaptability, communication, ethical judgment, accountability and personal development.

4. Organize each example using STAR

Write concise bullet points under Situation, Task, Action and Result. Pay particular attention to your personal actions, decisions and reasoning.

5. Practise answering aloud

An answer that looks clear on paper may sound disorganized when spoken. Practise delivering each response naturally without reading or memorizing it.

6. Prepare for follow-up questions

Be ready to explain what you were thinking, what alternatives you considered, how others responded and what you would do differently.

7. Complete a realistic mock interview

A structured mock interview can identify weak examples, missing details, unclear reasoning and delivery problems before your actual interview.

Essential Competency Interview FAQs

Is the ECI a behavioural interview?

Yes. An essential competency interview generally asks you to demonstrate competencies through real examples of your past behaviour. Interviewers use those examples to evaluate how you previously handled relevant situations.

What competencies are assessed during a police ECI?

The exact competencies vary by police service. They may include areas such as flexibility, relationship building, communication, self-control, self-assessment, teamwork, integrity, judgment, accountability and respect for diversity.

Always confirm the current list with the police service to which you are applying.

How recent should my ECI examples be?

Follow the timeframe provided by the police service. Some services establish a specific recency requirement. Waterloo Regional Police currently asks candidates to use situations from the past two years.

How many examples should I prepare?

Prepare at least one strong example for every identified competency and additional examples where possible. A broader example bank gives you more flexibility when the wording of a question differs from what you expected.

Can I use the same example more than once?

One experience may demonstrate several competencies, but repeatedly using the same story can limit the evidence you provide. Develop enough varied experiences to select the example that best answers each question.

Can I use examples outside of employment?

Yes. Examples can come from school, volunteering, community service, sports or other life experiences. The example still needs to demonstrate meaningful responsibility, judgment and personal action.

Should I memorize my ECI answers?

No. Know your examples and their important details, but avoid memorizing a script. You need to listen carefully, adapt your response to the question and answer follow-up questions naturally.

What is the difference between an ECI and a regular job interview?

A regular interview may include broad questions about your experience and suitability. An ECI is more structured and requires detailed behavioural evidence demonstrating specific competencies.

Final ECI Preparation Advice

Success in an Essential Competency Interview depends on more than knowing the STAR acronym. You must select experiences with enough depth, clearly explain your personal actions and demonstrate the judgment, accountability and self-awareness expected of a future police officer.

Start preparing early. Confirm the requirements of your target police service, build a strong bank of authentic examples and practise explaining your decisions under realistic interview conditions.
