Make experience visible
At experienced levels, correct definitions are the baseline. Strong interviews reveal judgment: what you noticed, what you prioritized, why you chose an option, and how the result was verified.
Build an evidence inventory before revising theory
- A difficult incident or failure you helped resolve
- A design decision with meaningful alternatives
- A migration, upgrade, or adoption challenge
- A security or compliance trade-off
- A performance, cost, or reliability improvement
- A disagreement or stakeholder conflict
- A mistake, missed assumption, or decision you later changed
- A process, automation, or mentoring improvement
Use EVIDENCE for complex answers
- Environment: the system, users, scale, and your role.
- Variables: constraints, risk, uncertainty, and competing goals.
- Investigation: data collected, hypotheses tested, and people involved.
- Decision: options considered and why one was selected.
- Execution: your contribution and how the change was controlled.
- Numbers or observable result: use verified measures when available; otherwise describe the observable outcome precisely.
- Controls: validation, rollback, monitoring, security, and communication.
- Evolution: what you learned and what you would change next time.
Prepare for depth, not breadth theatre
Choose four to six projects that collectively show operations, delivery, judgment, collaboration, and growth. For each one, prepare a two-minute overview and deeper branches for architecture, troubleshooting, security, cost, stakeholder, and failure questions.
Senior and architect signals
Senior candidates are expected to make work safer for others. Architect candidates are expected to connect requirements, systems, delivery constraints, and organizational consequences. Include governance, operability, migration, adoption, and failure—not only the ideal end-state diagram.
