Sample Answer
(S) On a user-content platform, we needed to support soft deletes for recovery, maintain audit history for compliance, and still honor GDPR hard-delete requests. (T) I designed the schema and APIs to handle these lifecycle states cleanly. (A) At the DB level, I added a deleted_at column and status enum to main entities for soft delete, and created separate audit tables (e.g., content_audit) with version, changed_by, and changed_at. All write operations appended to audit tables via DB triggers or application-level events. For GDPR, we introduced a separate erasure workflow: instead of just soft deleting, a background job anonymized PII fields and removed references, while keeping non-identifiable aggregates. APIs filtered out soft-deleted records by default, with an admin-only flag to include them. I also added an erasure_request table to track SLA (e.g., 30 days) and exposed status via API. (R) This approach allowed us to restore ~95% of accidental deletions within 30 days, passed an external audit with zero critical findings, and reduced manual compliance work by ~60% through automation.
Walk me through a recent multi-channel digital marketing campaign you managed end-to-end. How did you set objectives, choose channels, allocate budget, and measure success?
In your resume you note improving or optimizing [a process, KPI, or metric]. What specific baseline metrics did you start from, what steps did you personally take, and how did you verify that the improvement was due to your changes rather than external factors?
Based on your hydrology and irrigation engineering background, explain how you would estimate the irrigation water requirement for a kharif crop in a semi-arid region of Gujarat. Walk me through each step: from reference evapotranspiration estimation, crop coefficient selection, effective rainfall calculation, to arriving at canal discharge for a given command area.
In your civil engineering studies, what specific design coursework or project work did you complete related to irrigation channels or canals (e.g., design of lined/unlined canals, distributaries, minors)? Describe one such design in detail, including how you determined discharge, permissible velocity, section dimensions, and lining choice for Gujarat-type soil and climate conditions.
On your resume you mention working on a cross-functional project (e.g., involving multiple teams or stakeholders). Describe a situation from that project where priorities conflicted—how did you navigate the trade-offs and what was the final outcome?
