Why this role is hard · Ryan Mahoney

The real test here goes far past checking off engineering degrees or running facilitation sessions. You need someone who can enforce strict contract limits while turning complex utility needs into clear daily tasks for field teams. I have watched applicants shine in panel interviews by quoting interface control documents, only to completely shut down when two contractors argue over warranty work at an active depot. This job demands proof that they can trace hidden links between power infrastructure and vendor timelines without setting off expensive delays. They have to flag problems early enough that the grid operator never has to pause commissioning.

Active Listening

The disciplined practice of fully concentrating on, comprehending, and responding to stakeholders’ explicit and implicit communications without premature judgment. For an Interface Manager, it entails cognitively processing technical constraints, operational realities, and relational dynamics across functional boundaries, then verifying understanding through targeted reflection and actionable synthesis to align divergent priorities, mitigate coordination failures, and foster psychologically safe collaboration.

Positive indicators

  • Proposes targeted one-on-one sessions to bypass group dynamics
  • Suggests using dependency mapping to reveal hidden bottlenecks
  • Mentions formalizing assumptions for explicit stakeholder validation

Negative indicators

  • Immediately defaults to voting or majority rule without investigation

Deliverables

  • A short deck-and-walkthrough presenting your narrative, decision rationale, and stakeholder alignment strategy
  • Verbal defense of your tradeoff decisions and negotiation approach

Ground rules

  • Use only work you are permitted to share; anonymize sensitive vendor, client, or project details if necessary

Presents a coherent narrative of a past boundary dispute, explains their role in facilitating alignment, and describes a reasonable resolution process with clear stakeholder buy-in.
Below
Struggles to explain the conflict's root cause, defaults to authoritarian directives instead of facilitation, or cannot articulate how they balanced competing vendor priorities.

Response time

20 min

Positive indicators

  • Clearly frames the competing interests and boundary ambiguities at the outset
  • Demonstrates structured facilitation techniques (e.g., joint alignment sessions, explicit decision rights mapping)
  • Balances technical rigor with partnership preservation and long-term vendor relationships
  • Articulates tradeoffs transparently and explains how consensus was reached

  • Focuses only on the final technical outcome without explaining the negotiation process
  • Fails to address how collaboration was maintained during high-stakes conflict

Work Simulation Scenario

Scenario. You are mediating a boundary dispute between IT Security and OT Operations regarding data routing for a new microgrid SCADA network. Security demands strict packet inspection and zero-trust segmentation, while Operations requires low-latency telemetry for real-time grid control. You must reconcile conflicting protocols, define clear interface boundaries, and establish a unified control framework that survives audit and commissioning scrutiny.

Problem to solve. Design an interface governance approach that balances cybersecurity compliance with operational latency requirements, clarifying ownership of data routing and inspection handoffs.

Format

cross-functional-decision · 40 min · ~2 hr prep

Success criteria

  • Articulate a clear boundary between security monitoring and operational telemetry streams
  • Negotiate acceptable latency vs inspection tradeoffs
  • Establish documented accountability for interface handoffs and compliance sign-offs

What to review beforehand

  • SCADA network topology draft
  • Cybersecurity compliance framework requirements
  • Operational latency SLAs for grid control loops

Ground rules

  • You are facilitating the boundary definition, not drafting the architecture
  • Focus on governance and accountability, not deep packet-level engineering
  • Ensure both compliance and operational continuity are addressed

Roles in scenario

David Okoro, IT Security Architect (cross_functional_partner, played by cross_functional)

Motivation. Enforce zero-trust segmentation and comprehensive packet inspection to prevent lateral movement across control networks.

Constraints

  • Corporate security policy mandates deep packet inspection at all OT/IT boundaries
  • Audit requires documented access controls within 30 days

Tensions to introduce

  • Argue that latency is acceptable if it prevents grid compromise
  • Push for IT-managed firewalls controlling OT data flows
  • Question Operations' historical compliance with security protocols

In-character guidance

  • Be compliance-focused and risk-averse
  • Cite regulatory and audit requirements when pressured
  • Yield only if security boundaries and inspection responsibilities are explicitly assigned

Do not

  • Do not design the network architecture for the candidate
  • Do not escalate hostility or dismiss operational needs outright
  • Do not volunteer audit timelines unless asked

Priya Sharma, OT Operations Lead (cross_functional_partner, played by cross_functional)

Motivation. Maintain sub-50ms telemetry latency for real-time grid stabilization and inverter control.

Constraints

  • Grid control loops fail if packet inspection adds >20ms latency
  • Field technicians require direct diagnostic access during fault events

Tensions to introduce

  • Argue that strict inspection will cause cascading grid instability
  • Push for OT-managed routing with security monitoring only
  • Highlight historical outages caused by IT overreach

In-character guidance

  • Be operations-focused and latency-sensitive
  • Emphasize real-world grid stability over theoretical security models
  • Agree only if diagnostic access and latency thresholds are contractually protected

Do not

  • Do not solve the latency engineering problem for the candidate
  • Do not concede to security mandates without operational safeguards
  • Do not withhold fault-event access requirements when questioned

Scoring anchors

Exceeds
Precisely maps security vs operational boundaries, negotiates quantifiable latency/inspection tradeoffs, and establishes a clear, auditable governance framework that preserves both compliance and grid stability.
Meets
Identifies core latency and security conflicts, facilitates balanced discussion, and agrees on a conditional routing approach with documented ownership and escalation triggers.
Below
Conflates security monitoring with operational control, fails to establish clear accountability boundaries, or cannot secure mutual alignment without imposing technical mandates.

Response time

40 min

Positive indicators

  • Asks clarifying questions to quantify latency thresholds and inspection requirements
  • Clearly separates security monitoring boundaries from operational control handoffs
  • Facilitates structured tradeoff discussion without taking sides prematurely
  • Maps accountability for interface compliance and diagnostic access explicitly
  • Validates both compliance and operational constraints before proposing governance frameworks

Negative indicators

  • Guesses at acceptable latency or inspection thresholds without verification
  • Allows technical jargon to obscure accountability boundaries
  • Fails to distinguish monitoring from control responsibilities
  • Proposes unilateral routing decisions without cross-functional alignment
  • Avoids documenting interface ownership or compliance sign-off pathways
