Ryan Mahoney

Why this role is hard · Ryan Mahoney

The real challenge in hiring a subsystem CAD designer is finding someone who can keep complex spatial relationships straight while constantly working with structural and electrical teams. Raw drawing speed means nothing if you cannot listen to competing engineering limits, take full responsibility for every coordinate change, and speak up when a layout breaks safety clearances. Most applicants treat drafting like a solo translation job and fall apart when a reference file updates overnight or new battery electric bus charging codes force them to redraw entire systems under tight deadlines.

Imagine you discover a critical coordinate mismatch between civil grading plans and electrical conduit routing during a weekly cross-reference review. The structural team insists their baseline is correct, while field surveyors report discrepancies on-site. What steps would you take to investigate, how would you communicate your findings to both engineering leads and field supervisors, and what protocol would you implement to prevent version control conflicts moving forward?

Stage 3 · During Interviews

Where the hire is decided

Interview rounds use the competency and attitude questions outlined above, then add tests, work simulations, and presentations that reveal deeper evidence about how the candidate thinks and works.

Presentation Prompt

Talk us through how you would approach coordinating multi-discipline reference overlays to resolve spatial conflicts in a BEB maintenance pit. Discuss your reasoning for balancing independent design authority with cross-functional dependencies, particularly when reconciling vendor equipment envelopes with municipal right-of-way constraints. Slides are optional; talking through your reasoning is fully acceptable.

Format

  • No prepared slides required. Focus on articulating your step-by-step reasoning.
  • Clarify any assumptions you make about the hypothetical scenario before diving into solutions.

Scoring anchors

Exceeds
Proactively frames ambiguity, asks precise clarifying questions, and demonstrates robust, safety-first coordination strategies across disciplines.
Meets
Identifies key clashes, proposes reasonable resolution paths, and outlines clear communication protocols for cross-functional handoffs.
Below
Rushes to a layout without validating constraints, ignores compliance boundaries, or lacks a structured approach to multi-discipline coordination.

Response time

20 min

Positive indicators

  • Asks high-information clarifying questions about subsystem boundaries and vendor constraints before proposing solutions
  • Surfaces assumptions about coordinate systems and clearance tolerances early
  • Shows structured reasoning for prioritizing clashes and sequencing resolution
  • Balances independent design authority with appropriate engineering escalation

  • Assumes perfect alignment of reference files without verification steps

Work Simulation Scenario

Scenario. You are responsible for coordinating multi-discipline reference overlays for a BEB maintenance pit clearance layout. You've received civil, structural, and MEP reference files, but they contain overlapping zones and conflicting coordinate datums. The project manager wants a clash-free layout by end of week. Walk us through how you would diagnose the conflicts, determine the resolution path, and coordinate with the respective discipline leads to finalize the spatial layout.

Problem to solve. Develop a systematic approach to clash detection, cross-discipline coordination, and spatial resolution that balances independent design authority with engineering dependencies.

Format

discovery-interview · 40 min · ~2 hr prep

Success criteria

  • Identifies and isolates coordinate/datum mismatches across disciplines.
  • Proposes a structured clash detection and resolution workflow.
  • Balances independent spatial adjustments with necessary engineering sign-offs.
  • Communicates clear next steps and validation checkpoints.

What to review beforehand

  • Review multi-discipline CAD coordination best practices.
  • Understand typical clash detection workflows in transit infrastructure projects.

Ground rules

  • You will interact with a Civil Engineering Lead who holds specific project constraints.
  • Focus on your analytical and coordination process rather than producing a resolved model.
  • You have 40 minutes to map out your approach.

Roles in scenario

Civil Engineering Lead (informed_partner, played by cross_functional)

Motivation. Needs a designer who can independently resolve overlay conflicts without escalating every minor clash, while respecting structural and MEP safety margins.

Constraints

  • Will only provide data when explicitly asked.
  • Expects the candidate to understand typical clearance tolerances and coordinate transformation basics.
  • Will not approve spatial adjustments that compromise structural integrity or drainage.

Tensions to introduce

  • Civil grading plan uses a different vertical datum than the MEP conduit routing.
  • Structural overlay shows a support column that encroaches on the proposed maintenance pit access zone.
  • Project timeline pressure discourages lengthy coordination meetings.

In-character guidance

  • Provide precise answers to direct questions about grading, clearances, and structural boundaries.
  • Acknowledge trade-offs when the candidate proposes realistic compromises.
  • Maintain focus on safety and constructability constraints.

Do not

  • Do not volunteer coordinate transformation steps or clash resolution strategies.
  • Do not approve or reject proposed spatial adjustments outright; require justification.
  • Do not solve the multi-discipline alignment for the candidate.

Scoring anchors

Exceeds
Systematically isolates root causes of clashes, establishes a clear cross-discipline validation workflow, and proposes constructible compromises that respect safety and engineering boundaries.
Meets
Identifies major coordinate and clearance conflicts, proposes a logical resolution sequence, and engages discipline leads appropriately, though may miss minor validation steps.
Below
Makes unverified assumptions about overlay alignment, bypasses engineering consultation, or fails to prioritize safety-critical clashes.

Response time

40 min

Positive indicators

  • Asks targeted questions to isolate coordinate system discrepancies and overlay version mismatches.
  • Proposes a prioritized clash detection workflow that separates critical safety conflicts from minor aesthetic overlaps.
  • Establishes clear communication protocols with discipline leads to validate adjustments.
  • Demonstrates awareness of constructability and safety margins when proposing spatial compromises.

Negative indicators

  • Assumes all overlays are aligned to the same datum without verification.
  • Proposes unilateral spatial changes without acknowledging engineering sign-off requirements.
  • Overlooks critical safety clearances in favor of schedule pressure.
  • Fails to establish a structured resolution path or validation checkpoints.
