FDE COMMONS/by AIR

INTERVIEW READINESS

Show how you reason when the problem is incomplete.

FDE interviews reward pragmatic engineering under ambiguity. Practice the decision, not a memorized framework.

01

Discovery

Turn an ambiguous request into users, constraints, risks, and an observable outcome.

STRONG SIGNALAsks before solving; distinguishes stated request from operational job.
02

System design

Design across product, customer systems, security, data, operations, and rollout.

STRONG SIGNALNames boundaries, failure modes, tradeoffs, and what stays manual.
03

Production debugging

Diagnose a failure that could come from model, context, tool, data, code, or infrastructure.

STRONG SIGNALBuilds a timeline, tests hypotheses, and protects the customer while learning.
04

Build / code

Create a narrow working artifact under time pressure.

STRONG SIGNALShips readable, testable code and explains deliberate omissions.
05

Customer judgment

Navigate disagreement, scope, risk, and an imperfect path to value.

STRONG SIGNALBalances trust, speed, reversibility, and measurable learning.
06

Field learning

Turn a one-off deployment lesson into reusable product leverage.

STRONG SIGNALSeparates customer-specific configuration from a repeatable primitive.

YOUR EVIDENCE STORY

Bring one system you can interrogate deeply.

  1. What user outcome mattered?
  2. What constraint changed the architecture?
  3. What failed in production or testing?
  4. How did you diagnose it?
  5. What evidence proved the fix?
  6. What would you change for the next customer?
