Explain a Past BA Project
Part of the Business Analyst Roadmap
In short
'Walk me through a project you've worked on.' You'll almost certainly be asked this. Prepare it like a short story with a clear beginning, middle and end, and you'll walk in calm.
Walking an interviewer through a real project (from your portfolio or work) — the problem, your approach, what you found, and its impact — one of the most predictable interview questions.
Think of it like this
The story at family dinner
When your uncle tells the story of his first job, everyone listens because it has a setup, a problem, what he did and how it ended. Nobody wants every date and detail. Tell your project the same way.
Watch it happen
STAR for a project walkthrough
1/5Situation, 20 seconds: 'Our college canteen had 25-minute lunch queues and lost sales.'
The big ideas
What you need to know
Two to three minutes
Practise to fit. Long enough for substance, short enough that they can ask follow-ups.
Say 'I', not just 'we'
Interviewers want your contribution. Be honest about the team, but clear about what you did.
A result with evidence
Even an estimate counts if you explain how you measured it. Never invent numbers.
Use your portfolio
A case study from your portfolio works well if you have no job experience. Say it was a self-driven project.
Save yourself the pain
Common mistakes
Oops
Spending two minutes on background and 20 seconds on what you did.
Do this instead
Keep Situation and Task short. Spend most of the time on your Actions and the Result.
Oops
Inflating your role or results.
Do this instead
Be accurate. Follow-up questions quickly expose exaggeration, and honesty builds trust.
