Sample Answer
On my last project, I designed an Order Orchestration microservice in Spring Boot that sat between our web frontend and several downstream systems. Its core responsibilities were order validation, pricing calls, and orchestrating inventory reservations for about 40k orders per day. Tech‑wise, it was Spring Boot 2.x with Java 11, Spring Web for REST, Spring Data JPA on top of PostgreSQL, and Kafka for async events like “order-created” and “inventory-reserved”. We also used Redis as a short‑lived cache for pricing lookups. I kept the layers very clean: controllers handled only HTTP concerns and simple DTO mapping; services contained the business rules and orchestration across repositories and Kafka producers; repositories were pure Spring Data interfaces plus a small custom repository for a complex search query. We also had a thin domain layer with value objects for money and quantities. That structure made it easy to add a new payment provider in two sprints with almost no controller changes and kept test coverage around 85%.

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.
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.
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?
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?
