Professional Engineer Interview



1. Understand the Structure of the Interview

The IEM PI generally consists of three parts:

A. Submission of Documents

  • Full Training & Experience Report (T&E)
  • Summary of Training & Experience (STE)
  • Organization chart (showing your role)
  • Key project reports (usually 2–3 major projects)

B. Professional Interview (Oral Interview)

Normally 60–90 minutes:

  • Questions on your projects
  • Questions on engineering fundamentals
  • Questions on codes, standards, and safety
  • Questions on ethics (very important)
  • Questions to test whether you can take responsibility as a Professional Engineer

C. Engineering Essay

Usually 45–60 minutes:

  • One technical topic
  • One ethics/professionalism topic

You choose one topic and write.


2. Prepare Your Training & Experience Report (T&E)

Your T&E must show progression, not just tasks.

Focus on:

Your role

What decisions did you make?

Engineering judgment

What calculations, designs, troubleshooting or optimizations did you personally do?

Responsibility

Where did you:

  • sign off drawings?
  • check calculations?
  • manage safety risks?
  • manage contractors?

Challenges

Discuss real engineering problems:

  • equipment failure
  • safety hazards
  • design conflicts
  • scheduling issues

Explain how you solved them.


3. Prepare Project Reports

Pick 2–3 strong projects where you played a real engineering role.

Each report should include:

  • Project background & objective
  • Your specific responsibilities
  • Technical details (design, calculations, standards applied)
  • Safety considerations
  • Engineering decisions
  • Drawings, sketches, photos (if allowed)
  • Lessons learned

You must know every detail of these reports because the panel will ask deeply.


4. Master Your Engineering Fundamentals

Be ready to answer questions like:

  • Why did you choose this design?
  • What codes/standards did you follow?
  • What is the safety factor used and why?
  • Explain the failure mode if design is wrong
  • Troubleshooting scenarios
  • Material or equipment selection
  • Technical calculations (simple but fundamental)

If Mechanical:

  • thermodynamics, pumps, boilers, HVAC, pressure vessels, failure analysis

If Electrical:

  • earthing, fault level, protection, harmonics, load flow

If Civil:

  • soil, foundation, loads, codes, structural behaviours

If Chemical:

  • mass balance, heat transfer, process safety, equipment sizing

5. Ethics & Professional Conduct (Very Important)

Every PI includes ethics.

Be prepared to answer:

  • What would you do if your boss asks you to approve unsafe work?
  • How do you handle conflict of interest?
  • What is your responsibility as a future PE?
  • How do you ensure public safety?

Many candidates fail here.


6. Prepare for the Essay

Two categories:

Technical Essay

Write about:

  • engineering challenges
  • design considerations
  • new technologies
  • safety case

Ethics Essay

Examples:

  • responsibility of engineers
  • importance of integrity
  • sustainability
  • public safety

Tips:

  • Write clear structure: introduction → body → conclusion
  • Use real engineering examples
  • Stay formal and professional

7. Practice Common Interview Questions

Below are the most repeated questions:

About Yourself

  • Tell us about your engineering experience.
  • Why do you want to be a Professional Engineer?

Project-Based

  • What was the most critical decision you made on this project?
  • Explain your design/operation method in detail.
  • What were the risks involved?

Engineering Knowledge

  • Explain how ___ works.
  • What are the causes of failure for ___?
  • What standards apply to ___?

Ethics

  • What would you do if time or budget pressures force compromises on safety?
  • Would you sign off on work beyond your expertise?

8. Dress, Conduct & Communication

  • Formal attire
  • Bring your reports neatly arranged
  • Speak confidently, but not arrogantly
  • If you don’t know, say “I would refer to the standard / specialist”
  • Be honest — they can detect bluffing instantly

🔥 If you want, I can help you:

✔ Review your experience report
✔ Prepare sample answers
✔ Create a mock interview
✔ Draft your project report
✔ Suggest likely technical questions based on your discipline
