How to Answer — The STAR Method
Use the STAR structure to answer behavioural questions with a strong story:
- Situation: What was the context?
- Task: What was your responsibility?
- Action: What did you do?
- Result: What outcome/impact followed? (with numbers if possible)
What to Highlight in the Interview
- ✓List your shipped games with store links and download counts — this is your strongest proof.
- ✓State your engine (Unity, Unreal) and language (C#, C++) clearly; job ads filter on these.
- ✓Add your GitHub and itch.io portfolio links, and share a playable demo if you have one.
- ✓Quantify optimisation (FPS, memory, draw calls) and retention/revenue metrics.
- ✓Include hobby projects even if unfinished; employers want to see passion and hands-on experience.
What to Avoid
- ✕Not adding a shipped project or a portfolio/GitHub link.
- ✕Only naming the engine without explaining which systems you coded.
- ✕Leaving out optimisation and game metrics (FPS, retention).
Frequently Asked Questions
How should I prepare for an interview?
Study likely questions in advance, prepare a concrete example from your own experience for each (using STAR) and rehearse out loud.
How much should I talk in my answers?
Ideally 60–90 seconds per question. Too short seems disengaged; too long seems unfocused.
What if I get a question I do not know?
Be honest; say you do not know, but add how you would learn it or a similar experience. Making things up is the biggest mistake.
