A practical guide for Project Managers preparing for interviews, covering key numbers and outcomes.
When you're interviewing for a Project Manager role, it's easy to focus on your responsibilities, the projects you've worked on and the systems you use.
But one of the simplest ways to demonstrate the scale of your experience is to know your numbers.
A strong Project Manager should be able to confidently talk through the projects they've managed, including the value, duration, team size, challenges and outcomes.
You don't need to memorise a script. You just need to know your experience well enough to explain it clearly.
Here are some of the key numbers and details you should have at your fingertips before your next interview.
1. Know your project value
One of the first things an interviewer will want to understand is the scale of the projects you've managed.
Be prepared to talk about:
The overall project value
The value of projects you've personally managed
The size of your largest project
The value of your current or most recent projects
For example, saying you managed a major construction project is useful, but explaining that you managed a $25 million project from commencement through to completion gives the interviewer much more context.
If you've managed multiple projects, it can also be useful to explain the combined value of your portfolio.
2. Know your project duration
Project timelines can tell an interviewer a lot about your experience.
Be prepared to explain:
How long the project ran
What stage you joined the project
How long you were responsible for it
Whether you managed projects concurrently
A Project Manager managing a $10 million project over six months has a very different experience to someone managing a $10 million project over three years.
The more context you can provide, the easier it is for an interviewer to understand your experience.
3. Know your team size
Project management isn't just about managing a program of work, it's about managing people, contractors, consultants and stakeholders.
Think about the size and structure of the teams you've worked with.
You might be asked:
How many people were directly in your team?
How many subcontractors were involved?
How large was the wider project team?
Who did you report to?
Which consultants and stakeholders did you work with?
There's no magic number that makes someone a strong Project Manager. What matters is being able to demonstrate the complexity of the environment you've operated in.
4. Know the size of your portfolio
If you're managing multiple projects, make sure you know the numbers.
How many projects are you currently responsible for?
What's their combined value?
What stage are they at?
What sectors or project types do they cover?
Being able to clearly explain your portfolio gives an interviewer an immediate understanding of the workload and level of responsibility you're accustomed to handling.
5. Know your biggest challenges
This is where the conversation usually becomes more interesting.
Most projects don't go exactly to plan, and interviewers will often want to understand how you respond when things become difficult.
Think about a few examples before your interview:
A project that went off track
A difficult stakeholder
A major variation
A subcontractor performance issue
A delay or programme issue
A budget challenge
A difficult commercial decision
Most importantly, don't just explain what happened.
Explain what you did.
Rather than saying:
"The project was delayed."
Explain what caused the delay, how you responded, who you worked with and what the eventual outcome was.
6. Know your biggest variation
Variations are a normal part of many projects, so be prepared to discuss them.
Know the value of your biggest variation and, more importantly, the circumstances around it.
What caused it?
How did you assess the impact?
How did you communicate it to the client?
How did you manage the commercial implications?
This can be a great opportunity to demonstrate your commercial awareness and decision-making skills.
7. Know the outcome
Don't forget the most important part of the story: the result.
When talking about a project, try not to finish with:
"And then we completed the project."
What was the outcome?
Was it delivered:
On time?
Within budget?
Ahead of programme?
With cost savings?
To a strong client outcome?
Despite significant challenges?
If something didn't go perfectly, that's okay too.
Being able to explain what you learned and what you would do differently can demonstrate maturity and self-awareness.
Know your contribution
Perhaps the most important thing to remember in a Project Manager interview is the difference between what the project team did and what you did.
It's easy to talk about a project using "we":
"We delivered the project."
"We managed the subcontractors."
"We worked with the client."
But the interviewer needs to understand your individual contribution.
What decisions did you make?
What problems did you solve?
What did you take ownership of?
What changed because of your involvement?
Your CV might get you the interview, but being able to clearly explain your experience is what helps you stand out.
Before your next Project Manager interview
Take 10 minutes before the interview and write down the key details of your recent projects.
Project value.
Project duration.
Team size.
Portfolio size and value.
Biggest variation.
Biggest challenge.
Delivery outcome.
You don't need to memorise every detail.
Just make sure you know your projects, know your numbers and know your contribution.
That preparation can make a big difference when you're sitting across the table from an interviewer.
