Why pre-screen 3D design interns before the portfolio review
Every intern portfolio in this field looks competent, because the tutorials are excellent and the renders are lit for you. What separates candidates is whether they can say why the topology is built that way, what they would change, and what happened when someone told them it was wrong. A short screen asks them to talk through one decision, which is the fastest way to see who understands their own work.
What actually matters when screening 3D Design Intern candidates
- 01
Portfolio
Ask to walk through two or three reels or ArtStation pieces: which models they built from scratch, software used (Blender, Maya, Cinema 4D, ZBrush), and render engine.
- 02
Craft and rationale
Probe topology decisions, UV layout, poly budgets, PBR texturing in Substance Painter, and lighting setups in KeyShot, Cycles, or Unreal; ask why those choices.
- 03
Feedback and iteration
Test how they handled art direction notes on a university brief or freelance job: silhouette changes, retopology requests, or scrapped concepts, and turnaround speed.
- 04
Working with the brief
Look for evidence of reading a brief: deliverable specs, file formats (FBX, OBJ, USD), naming conventions, deadlines, and asking clarifying questions before modelling.
Pre-screening questions to ask 3D Design Intern candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Work they can explain
3 questions01Can you describe a project where you applied your 3D design skills?
Listen forA finished piece they can talk through, including a decision they would make differently now.
Projects described by tool used rather than intent, or nothing finished beyond exercises.
02Do you have any experience creating 3D models for games or virtual reality?
Listen forAwareness that real-time work has polygon and texture budgets, even if only from coursework.
Real-time constraints unknown, or high-density models presented as game ready.
03Have you ever taken part in a 3D printing project?
Listen forSomething physically printed, with wall thickness, supports or tolerance learned the hard way.
Models designed with no printing constraints in mind, or nothing ever taken off the screen.
Beyond tutorials
4 questions04Which 3D modelling software are you fluent in using?
Listen forOne package used properly rather than five listed, with the workflow inside it described in detail.
Long software lists with no depth, or fluency claimed from a single short course.
05Do you have hands-on experience with CAD software?
Listen forParametric modelling understood as different from mesh work, with dimensions driven by constraints.
CAD and mesh modelling treated as the same thing, or geometry drawn without dimensions.
06What is your approach to creating detailed production drawings?
Listen forAwareness that a drawing has to be readable by someone who will manufacture from it.
Drawings treated as a rendering step, or dimensioning and tolerance conventions unknown.
07Do you have experience with rapid prototyping?
Listen forIteration through physical or digital prototypes, with what each version taught them described.
One version produced and presented, or prototyping described only in theory.
Takes criticism well
3 questions08How do you handle feedback and criticism on your design work?
Listen forA specific piece of criticism they acted on, and one they questioned with a reason.
Feedback described as always welcome with no example, or defensiveness about past critique.
09Do you find it challenging to turn 2D references into 3D models?
Listen forHonest description of where it gets difficult, with their method for resolving ambiguous references.
The difficulty dismissed entirely, or references followed without questioning inconsistencies.
10Do you have experience preparing and presenting design proposals?
Listen forWork presented to someone who was not a friend, with the reasoning explained rather than the render shown.
Presentation limited to sharing images, or no experience explaining work to anyone.
Works to a brief
2 questions11Have you taken part in a team-based 3D design project?
Listen forA shared project with their own part identified, and file naming or asset conventions followed.
Only solo work, or shared projects where their contribution cannot be identified.
12How do you keep up with new techniques and tools in 3D design?
Listen forSpecific sources named, with something recent they learned and applied to their own work.
Learning described as following social feeds, or nothing new tried in the last year.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Portfolio
35%5Shows self-authored assets with wireframes and turntables, states exactly which parts were theirs versus tutorial or kitbash sources.
Craft and rationale
25%5Explains clean quad topology, sensible UV packing, and material or lighting reasoning tied to the end use of the asset.
Feedback and iteration
25%5Describes specific revision rounds, shows before and after versions, and treats critique as material rather than defending the first pass.
Working with the brief
15%5Clarifies scope early, delivers named and organised files to spec, and flags timeline risk before the deadline slips.
Every intern portfolio looks competent because the tutorials are excellent. A one-way video screen asks them to explain one decision.

Process basics
How long should a pre-screening round for this role take?
Ten minutes across eight questions, answered async alongside a portfolio link. Enough to hear them explain their own work and see how they take feedback before you review anything.
What should I expect from someone with no commercial experience?
Coursework and personal projects are fine at this level. What matters is whether they finished things, can explain their choices, and have worked to a brief set by somebody else.
Evaluating answers
What is the strongest signal when screening an intern?
Explaining a modelling decision in their own work. Interns who understand what they built answer specifically. Anyone who cannot has followed a tutorial and rendered the result.
How do I judge how they take feedback?
Ask about criticism they received and disagreed with. Good answers describe the reasoning on both sides. Defensiveness at intern level tends to get worse under real deadlines.
