The scenario
The session opens with a motivation question, why physical products over another design path, then shifts into a lighter portfolio moment, explaining a material or CMF decision on a project you bring up.
From there it moves into an ergonomics question, how you'd test whether a grip is comfortable across a range of hand sizes, and closes on a behavioral question about a design that changed late because of a manufacturing or user-testing finding. Motivation, portfolio, ergonomics, and a late-stage pivot, covered without a break between any of them.
What gets covered
Expect background and motivation, a lighter-weight product walkthrough than a full resume-based session would run, a manufacturing or ergonomics question grounded in a real constraint, and at least one behavioral scenario centered on a late design change.
Collaboration questions show up too, usually about disagreeing with an engineer over a manufacturability concern, since that back-and-forth is a real, constant part of the job most narrower practice types don't test directly.
Scoring
How scoring applies here
The STAR-structure penalty is worth watching closely in this session, since the behavioral portion, describing a design that changed late in the process, is exactly where that structure matters most. An answer that jumps straight to the final design without laying out what actually triggered the change and what action you took loses points under the same penalty system that applies across every Intervieux interview.
Technical gets scored on the ergonomics and manufacturing question specifically, checking whether the reasoning was grounded in something real rather than a general design philosophy.
Frequently asked questions
Does the manufacturing question here go as deep as a dedicated technical session would?
Not quite. Comprehensive touches a manufacturing moment as one part of a broader spread, while the technical practice type stays on that reasoning throughout with checkable math.
Will it ask about ergonomics, not just aesthetics?
Yes, as one section among several, testing whether a design decision is grounded in how people actually use the object.
Should this replace running the narrower practice types on their own?
For a fast final rehearsal it's a reasonable substitute, since one sitting touches the same range of ground several standalone sessions would otherwise cover separately.
Does it cover disagreements with engineers over manufacturability?
Yes, as part of the collaboration questions, since that back-and-forth is a real, constant part of an industrial designer's actual job.
Will the manufacturing question include real checkable math?
It's lighter than the technical practice type's dedicated tolerance or wall-thickness math, but it still tests whether your reasoning is grounded in something real, not just design philosophy.
Does this replace scheduling separate portfolio, manufacturing, and behavioral sessions?
It can substitute for all three when time is short, since it covers the same ground in one continuous conversation rather than three separate ones.
