CBA's purpose and what it means for your interview

CBA's purpose is "Building a brighter future for all." That could describe a lot of organisations, so look at its strategy as well. CBA's 2026 annual review says it's focused on "building tomorrow's bank today for our customers", and names continued investment in technology and AI as a priority, along with deeper customer relationships and strong risk management.

When you explain why you want to join, connect your reasons to something CBA is actually doing. "I want to help people with their finances" could be said about any bank. "I'm interested in how CBA is protecting customers from scams, and I'd like to work on that" gives the interviewer something specific to ask you about.

CBA and technology

Technology comes up often in what CBA says about itself. Its 2026 annual review says AI "is already changing what customers expect and how work gets done". Before your interview, spend some time in the CommBank app so you know what it does, and read what CBA says about technology and AI in its latest annual review or results. That's worth doing even for a role outside technology, since it's a big part of where the bank says it's heading.

CBA's values and what each one looks like in an answer

CBA has three values: Care, Courage and Commitment. Its description of Commitment includes working together and doing what's right, so those two have their own cards below. For any of them, a specific story with a clear result tells the interviewer more than calling yourself caring or brave.

Value 01
Care
What this looks like in an answer
CBA says "we care about our customers and each other" and "we serve with humility and transparency". In an answer, that means noticing what someone needed and doing something about it.
How to show it
Use a time you worked out what someone actually needed, which wasn't always what they first asked for. Customer service work is a good source, but uni, sport and volunteering work too. A good story has three parts: you noticed something was wrong, you took it on, and the person was better off because of it. If it involved helping someone with money, such as a budget, a bill or a payment problem, even better.
Value 02
Courage
What this looks like in an answer
CBA describes this as having "the courage to step in, speak up and lead by example". In an answer, that means raising a concern or questioning a decision when staying quiet would have been easier.
How to show it
Describe a time you raised a concern or questioned a decision, at work, at uni or in a club. Show that you had reasons and evidence, and that you raised it respectfully. Say what happened after you spoke up, even if the decision didn't change.
Value 03
Commitment
What this looks like in an answer
In CBA's words, "We are unwavering in our commitment", and "we do what's right and we work together to get things done". This card is about getting things done: doing what you said you'd do, even when it got hard.
How to show it
Use a story where keeping a promise turned out to be harder than you expected, and you kept it anyway. Make the promise and the obstacle clear. For example: "I said I'd have the analysis done by Friday. On Wednesday we found the data was wrong, so I rebuilt it over two evenings and still had it done on Friday."
Part of Commitment
Working together
What this looks like in an answer
From CBA's description of Commitment: "we work together to get things done". In a bank the size of CBA, a lot of work involves people from other teams with their own priorities.
How to show it
Say what you did to bring together people with different priorities or ways of working, sort out a disagreement or share what you knew. The group should have done well because of how you helped it work together. Carrying a group that didn't pull its weight is a different story, better kept for a question about pressure or workload.
Part of Commitment
Doing what's right
What this looks like in an answer
Also from CBA's description of Commitment: "we do what's right". Banks are closely regulated and look after other people's money, so have a story about honesty ready.
How to show it
Choose a time when there was an easier option that wasn't quite right, and you didn't take it. Owning up to a mistake and fixing it before anyone asked works well here, and it's often easier to talk about than a dramatic ethical dilemma.

Graduate program streams

CBA's graduate program runs for 12 to 24 months, depending on the program, with rotations through different areas, and you're a permanent employee from day one. Its careers page groups graduate roles into these areas:

  • Technology & AI: streams in Engineering, Cyber Security, Advanced Analytics, and Data Science & AI. Be ready for technical questions as well as behavioural ones.
  • Banking Products: the Product Management and CommSec streams. Know the main products in the CommBank app, and if you're applying for CommSec, how buying and selling shares works.
  • Relationship Management: roles in Business Banking and in Institutional Banking & Markets, working with business and corporate customers. Read up on what Australian businesses are dealing with at the moment.
  • Finance & Accounting, and Procurement: the teams that look after the bank's own numbers and what it buys. Be ready to explain numbers clearly to people who aren't accountants.
  • Risk Management: the teams that manage credit, operational and other risks. Be ready to talk through a decision you made when you couldn't be sure how it would turn out.
  • Other areas: Regional and Agribusiness Banking, and Marketing and Corporate Affairs. Check the careers page for what each one involves and where the roles are.

The selection process

1
Online application
CBA says the form takes about 10 minutes. Have your CV and your latest academic transcript ready before you start. If it asks why you want to join, give a reason that's particular to CBA.
2
Online assessment
If you meet the eligibility criteria and your application goes through, you're invited to an online assessment. CBA doesn't say much about what's in it, so read the invitation carefully and do it somewhere quiet where you won't be interrupted.
3
Digital interview
You answer a series of short, pre-recorded questions on camera, and you have 48 hours to finish once the invitation arrives. Use STAR, do a practice recording on your phone first, and don't leave it to the last hour.
4
Assessment centre
If you get through the digital interview, you're invited to an assessment centre, online or in person, with activities and interviews with leaders from the business. In group activities, take part, build on other people's ideas and help the group finish on time. In the interviews, use your STAR stories and know why you want to join CBA.
5
Offer and start date
CBA says it keeps in touch after each stage to let you know if you're progressing. If you get an offer, the program starts in mid-February the following year.

Practise your answers out loud before your CBA interview

InterviewZap asks you behavioural questions based on your CV and the job description, and after every answer shows you what was missing and a better way to say it. Answer by typing or out loud. Voice mode is a good way to get used to saying your stories.

CBA graduate interview questions to practise

Use the STAR method for the behavioural questions. The practice questions below are based on CBA's values. Practise with them to get your stories ready, whatever the wording on the day.

Questions 1–10 · To practise out loud
Question 01
"Tell me about a time you went out of your way to help someone, such as a customer, a colleague or someone in your community."
What a good answer shows
Care: that you help people beyond what's expected of you.
How to answer it
Choose a time when nobody asked you to help and the other person was clearly better off because you did. It doesn't need to be dramatic. Be specific about what you noticed, what you chose to do and how it turned out. "I'm a caring person" on its own gives the interviewer nothing to go on.
Question 02
"Describe a time you had to challenge a process or decision that you believed was wrong."
What a good answer shows
Courage: that you'll speak up when something looks wrong, and do it well.
How to answer it
Use a real disagreement and don't water it down. Show that you raised it with evidence, with respect for the people involved, and with an alternative in mind. You don't need to have won the argument. It's enough to show that you raised it well and followed it through.
Question 03
"Give me an example of a time you committed to something difficult and followed through."
What a good answer shows
Commitment: that you do what you said you'd do, even when it gets hard.
How to answer it
Describe the commitment, what made it hard and what you did to keep it. Give the most time to how you got past the obstacle. If keeping your word didn't cost you anything, choose a different story.
Question 04
"Tell me about a time you worked effectively with people who had very different priorities from your own."
What a good answer shows
Working together: that you can get things done with people who want different things from you.
How to answer it
Say who was involved and what each person or group wanted, specifically. Then walk through what you did to find common ground. Show that you understood why the other people wanted what they wanted, and say what the group achieved in the end.
Question 05
"Why CBA? Why not another bank or financial services firm?"
What a good answer shows
That you chose CBA for reasons you can explain, and that you know what makes it different from other banks.
How to answer it
Pick something specific, such as CBA's strategy, its work on technology and AI, or the program you're applying for, and connect it to your own interests. The CommBank app is a useful example. Know what it does and have a view on what you'd improve. If your answer would work just as well for Westpac or ANZ, rewrite it.
Question 06
"Describe a time you identified a better way of doing something and drove the change."
What a good answer shows
Initiative: that you look for better ways of doing things and see them through.
How to answer it
Say what the problem was, why it was worth fixing, what you suggested and what happened when you made the change. Put a number on the improvement if you can. "We cut the time it took from three days to one" is much clearer than "we made the process more efficient".
Question 07
"Tell me about a time you received feedback that was hard to hear. How did you handle it?"
What a good answer shows
That you can take criticism and do something useful with it.
How to answer it
Be honest about how you reacted at first. It's fine to say it stung or surprised you. Then say what you did next: how you thought it through, what you decided was fair, and what you changed. The change in what you do is the most important part of this answer, so make it specific.
Question 08
"How do you think technology is changing what it means to be a good bank?"
What a good answer shows
That you've thought about where banking is going, whatever stream you're applying for.
How to answer it
Talk about one or two specific changes rather than technology in general: banks using AI to spot fraud and scams, faster payments, or open banking, which lets customers share their banking data with other providers. Then connect it to what CBA says it's doing. A clear opinion you can explain is better than a list of trends, for example: "I think banks will be judged more and more on how well they protect customers from scams, and that's the work I'd like to do."
Question 09
"Describe a time you had to deliver something under real time pressure. How did you decide what came first?"
What a good answer shows
That you can decide what comes first when there isn't time to do everything.
How to answer it
Describe the deadline, then explain how you decided what to do first, what you simplified or dropped, and how you told people. Spend most of your answer on why you made those choices. "I worked hard and got it done" doesn't answer the question.
Question 10
"Tell me about a time you had to learn something new quickly to contribute effectively."
What a good answer shows
That you can pick things up quickly. A graduate program with rotations means starting in a new area more than once.
How to answer it
Say what you needed to learn and how long you had, then be specific about how you went about it: where you learned from, how you checked you'd understood, and when you started being useful. A method you can describe is more convincing than speed alone, because you can use it again in each new rotation.
Before the interview

Use the CommBank app and read what CBA says about its strategy. Have a view on where Australian banking is heading. And prepare at least two stories for each of CBA's values, including working together and doing what's right.
