Coding & Scripting Interview

45 min

Python or VBA script to generate a parametric part, evaluate performance metrics.

Behavioral & Collaboration Interview

1 hour

STAR questions on cross‑team projects, conflict resolution, and stakeholder communication.

Senior Design Review

1.5 hours

Presentation of a past product case study, critique of design decisions, and sustainability assessment.

Portfolio Review & Design Exercise

Present your work and defend your design decisions

What to Expect

Portfolio reviews typically last 30-60 minutes. You'll walk through 2-3 case studies from your portfolio while the interviewer asks questions about your process, decisions, and outcomes.

Key focus areas: design thinking, collaboration, problem-solving, and ability to articulate choices.

Structure Your Case Studies

Problem statement

What were you solving?

Your role

What did you specifically do?

Process

Research, ideation, iteration

Design rationale

Why did you make those choices?

Results

Metrics, feedback, outcomes

Learnings

What would you do differently?

Common Portfolio Questions

•"Walk me through this project from start to finish."
•"Why did you choose this design direction over alternatives?"
•"How did you handle conflicting feedback from stakeholders?"
•"What would you do differently if you could redo this?"
•"How did you measure success for this project?"

What Interviewers Look For

✓Clear rationale for every design decision
✓Quantifiable impact metrics (e.g., % weight reduction, cost savings, usability score)
✓Demonstrated proficiency in SolidWorks and rapid prototyping tools
✓Alignment of design with user needs and manufacturing constraints

Common Mistakes to Avoid

⚠Prioritising aesthetics over functional ergonomics
⚠Omitting user testing data or empathy insights
⚠Neglecting manufacturing constraints in early design stages
⚠Failing to quantify design impact with concrete metrics

Preparation Tips

Select 3–4 projects with full lifecycle documentation and annotated design rationale
Compile pre‑ and post‑launch metrics (ergonomics scores, cost, time‑to‑market)
Rehearse explaining trade‑offs between material, cost, and performance
Update portfolio with latest SolidWorks plugins (e.g., Simulation, Sheet Metal) and material libraries
