Top 5 Effective dating Interview Questions
Browse 5 real-world technical and behavioral interview questions about Effective dating. Review scenarios, edge cases, and architectural best practices.
A new version of the diagnosis code set takes effect part-way through your financial year. What has to happen across the systems that code and bill?
When a diagnosis code set changes mid-year, healthcare billing systems must select the version by date of service, then update payer rules, authorisations, contracts and reports that copied those codes. Trend data needs an explicit bridge.
The business wants to change a rating factor next Monday. Walk me through what actually has to happen.
In a filed environment the rate is a regulated artefact rather than a configuration value, so the change is versioned by state and effective date, applies to business written from that date rather than to everything, and must leave every existing quote and policy reproducible against the version that priced it.
You are building the payer side. How do you configure benefits so a plan change does not need a code release?
Separate the adjudication engine from effective-dated, immutably versioned configuration, resolve config by date of service rather than by today, hold accumulators as a reversible ledger of contributions, adjust decisions by replacement rather than edit, and release config through a replay harness.
A broker asks you to backdate a cover change to three months ago. How do you model the policy so that works?
A backdated endorsement in an insurance policy needs a bitemporal model: effective date for when cover changes and recorded date for when the insurer learned it. Store append-only versions so cover, premium and documents can be rebuilt for any past date. Use this policy administration answer to show the decision, trade-off, and evidence rather than a memorised definition.
How do you turn what the business tells you into a domain model that holds up once the exceptions arrive?
Model the state changes and invariants rather than the nouns the business names, and go looking for reversal, amendment, partial completion and manual override before committing to a shape. Domain-driven design earns its keep where rules are contested; on CRUD and reporting it is ceremony.
