There are two different interview-related moments in NAV CANADA’s published air traffic control selection process. After the approximately six-hour regional cognitive test, successful candidates are invited to a 15-minute pre-screening interview on the same day. A separate half-day assessment centre includes an interview alongside individual and group exercises. NAV CANADA’s official selection page explains both.

NAV CANADA pre-screening vs assessment-centre interview
On a narrow screen, swipe the table horizontally to see all columns. Keyboard users can focus the region and scroll sideways.
| Stage | Employer's published description | Do not confuse with |
|---|---|---|
| Online assessment | Earlier remote, timed test; approximately 30 minutes | An interview or a job offer |
| In-person cognitive test | Regional testing, approximately six hours; successful candidates invited to a 15-minute same-day pre-screening interview | The separate half-day assessment centre |
| Assessment centre | Half-day session with group and individual exercises plus an interview | The earlier 15-minute pre-screening |
| Language testing, if required | Possible third-party assessment over the telephone | The bilingual assessment-centre session |
The in-person test guide explains the cognitive stage, and the assessment-centre guide covers the later half-day session. Passing any one stage does not guarantee the next invitation. NAV CANADA schedules and selects candidates based on its process and operational requirements.
What NAV CANADA actually publishes about interview content
The employer states that the assessment centre includes an interview to assess candidates’ skills, abilities and attitudes. It specifically advises candidates to discuss their academic and work experience and their interest in an air traffic control career.
Its current public selection page does not disclose the complete interview questions, confidential marking rubrics, named competency scoring weights or an official answer framework. The list below is therefore editorial preparation, not a prediction of actual questions:
- Explain why the role appeals to you and what you have learned about safety-critical, shift-based aviation work.
- Choose one real example of working with others and explain what you personally did.
- Reflect on a mistake or feedback you received and how you improved your process.
- Describe a time you handled competing priorities while communicating accurately.
NAV CANADA’s tower controller, area controller and flight service specialist pages help distinguish roles. You do not need to invent aviation experience you do not have.
Free original interview preparation: two reflection exercises
The prompts below are original educational prompts, not NAV CANADA questions, interview transcripts, scoring guides or evidence of what will appear in your session. They have no pass/fail grade.
Exercise 1 - Describe feedback you used
Think of a time a teacher, colleague or supervisor corrected something you did. In 60-90 seconds, explain what changed because of that feedback. Use a truthful example rather than memorizing a fictional ideal answer.
Show an example STAR-L answer framework
Situation: Identify a real task and its context. Task: State your responsibility. Action: Describe the feedback and the specific change you made. Result: Give an observable effect, without inventing numbers. Lesson: Explain how you apply that lesson today. STAR-L is an optional independent structure, not NAV CANADA's official marking rubric.
Exercise 2 - Make a decision under conflicting deadlines
Select a genuine situation in which two requests competed for your time. Describe how you clarified the deadlines, chose a sequence, communicated your decision and checked the result.
Show a concise self-review checklist
Did I identify the facts and my actual responsibility? Did I explain why one task came first? Did I say whom I informed? Can I describe a real outcome and one improvement? If you cannot answer truthfully, choose another genuine event. This is not a confidential employer scenario.
A structure such as Situation, Task, Action, Result, Lesson (STAR-L) can help you organize your thoughts, but NAV CANADA has not published it as an official interview scoring methodology. Avoid writing scripted accounts of events that never happened.
Practical preparation without guessing the interview format
Confirm whether your invitation is for the same-day 15-minute pre-screening or the assessment-centre interview. Follow any instructions about venue, arrival time, identification, accessibility arrangements, language and permitted materials. Do not assume every session is virtual, in person or conducted in the same language.
For bilingual positions in the Montreal Flight Information Region, NAV CANADA says the assessment-centre session is bilingual. Possible telephone language testing by a third party is a separate step. See language requirements.
If you wish to practise general aptitude skills as well, start with 30 original free questions or the NAV CANADA free-first guide. These are not interview simulators and no commercial product is required.
After the interview: how to interpret the next step
NAV CANADA states that selected candidates receive an offer before their course start date and must meet relevant medical and licensing, security-clearance and drug-testing requirements before employment. That does not mean attending or passing an interview guarantees an offer.
Check Workday and the personal email address associated with your application. There is no universal public deadline by which every candidate must hear back. See assessment results and selection timeline.
