Interview room
Design PII handling: encryption, masking, RBAC, audits, erasure for GDPR/CCPA-style needs.
Basics
PII classification; defense in depth; masking vs hashing vs tokenization; restricted zones vs masked marts. Encryption is necessary not sufficient.
Prompt
Classify, encrypt, mask, RBAC, audit, erase, minimize copies, break-glass.
Good
Tags, zones, masked views, roles, audit sinks, lineage-driven erasure.
Clarify/scope
Field inventory, retention overrides, ML needs. Out of scope: full legal opinion.
Scoring lens: Handle PII Data Securely
Interviewers reward incident-first teaching, a clear control loop, and named owners. Tool logos without that loop score poorly.
Weak vs strong answers on Handle PII Data Securely
Weak: list products. Strong: tell the failure story, define the mechanism, draw the path, state rollout and monitors.
Scope control
Say what is out of scope for v1. Come back only if follow-ups demand it. This is a seniority signal for Handle PII Data Securely.
Clarifying then committing
Ask a few high-use questions about SLAs, owners, and scale, then sketch. Endless questions without a diagram look evasive.
Tokenization service sketch
A small privileged service maps email to token. Silver stores tokens. Support UI resolves after break-glass. Analytics never needs raw email for ordinary joins.
Access review cadence
Quarterly remove stale restricted grants. Phished accounts with ancient grants are common breach paths. Schedule reviews like you schedule compaction.
Erasure residual risk
Backups and cold storage may retain PII until TTL. Document residual risk honestly with counsel. Overpromising global instant delete destroys trust later.
Interview framing detail 1
For lb-sd-28, spend the first minutes making the problem concrete: who gets hurt when this fails, what SLA is implied, and what is explicitly out of scope. Then teach the prerequisite concept before proposing boxes. A candidate who names vendors first usually loses the plot. Write two clarifying questions on the board and answer them with assumptions if the interviewer shrugs. Keep the first diagram small enough to redraw when a follow-up changes a constraint.
