Custom Solution Development Questions

Focuses on designing and delivering bespoke technical solutions to meet specific customer or project requirements. Candidates should explain how they gather requirements, translate needs into technical designs, build prototypes, iterate with stakeholders, validate solutions, and deliver production quality implementations. Discussions may include architectural decision making, trade off analysis, integration with existing systems, customization of third party software, testing strategies, documentation, and how to measure success and maintainability. Provide examples of complex customizations, how constraints were managed, and how technical and non technical stakeholder feedback was incorporated.

You inherit a custom solution with poor documentation, flaky deployments, and frequent outages. Provide a prioritized remediation plan with short-term quick wins (bring system to known-good), medium-term stabilizations (introduce CI/CD, monitoring), and long-term improvements (refactoring, documentation, runbooks). Include how you'd communicate the plan to leadership.

You need to build a throwaway prototype to validate authentication and SSO integration for a customer that uses Active Directory + SAML. Describe the minimal prototype architecture, tools you would use to run it in a sandbox, how you'd collect feedback, and what success criteria you'd define to move from prototype to full design.
HardSystem Design
45 practiced
For a CRM that forbids schema changes to the vendor-managed database, design an architecture to implement customer-specific extensions while remaining upgrade-safe. Consider patterns such as extension tables, an external metadata layer, event-driven synchronization, or a proxy API layer, and analyze performance and consistency trade-offs.

Compare Git branching strategies (Gitflow vs trunk-based development) and recommend which one is more appropriate for a fast-moving custom solution delivered by multiple teams with frequent patches. Explain impacts on release cadence, CI pipeline complexity, and hotfix management.
HardSystem Design
58 practiced
Architect a secure cross-region integration for systems subject to different privacy regulations (GDPR in EU, CCPA in California). Detail data residency, encryption at rest/in-transit, consent propagation, anonymization techniques, audit logging, and how you encode regulatory constraints into deployment and contractual controls.
