Q1. How do you handle disagreements during design discussions?
Answer:
I focus on technical facts, business requirements, and measurable outcomes rather than personal preferences. I encourage open discussion, present pros and cons of each approach, and support decisions with data, architecture principles, and operational considerations. If needed, I build a proof of concept to validate assumptions before making a final recommendation.
Q2.Have you participated in system design reviews?
Answer:
Yes. I regularly participate in design reviews where we discuss service boundaries, API contracts, database design, security requirements, deployment strategies, scalability concerns, and integration patterns. My role is to identify risks, suggest improvements, and ensure the design aligns with architectural standards and best practices.
Q3. How do you actively participate in architectural and design discussions?
I actively participate by understanding both the business requirements and technical constraints before proposing solutions. During design discussions, I evaluate different approaches, identify trade-offs, consider scalability, security, performance, maintainability, and operational impacts. I collaborate with architects, product owners, QA teams, and other developers to ensure the proposed solution aligns with the existing architecture and long-term business goals
Q4. Can you give an example of an architectural decision you influenced?
In a previous project, a service was making multiple synchronous calls to downstream systems, causing high latency and occasional timeouts. During architecture discussions, I proposed moving to an event-driven approach using Kafka for non-critical processing. We analyzed the trade-offs, updated the design, and implemented asynchronous communication. This reduced API response times significantly and improved system resilience during peak traffic.
(STAR Format)
Situation:
Our order-processing system was experiencing performance issues during peak traffic.
Task:
We needed to improve response times without redesigning the entire platform.
Action:
I analyzed the architecture and identified that synchronous communication with downstream services was causing bottlenecks. Since Kafka was already part of the ecosystem, I proposed an event-driven approach where requests were published to Kafka and processed asynchronously. I documented trade-offs, reviewed the design with architects and stakeholders, and led the implementation.
Result:
API response times decreased from several seconds to under 500 milliseconds, throughput increased significantly, and the solution was implemented without major architectural changes.

What is Kanban in Agile?
Kanban is an Agile methodology focused on visualizing work, limiting work in progress (WIP), and continuously improving the flow of work.
Unlike Scrum, Kanban does not require fixed-length sprints. Work items are pulled through the system continuously.
When Kanban is Preferred
Kanban works well for:
- Support Teams
- Production Issues
- Bug Fixes
- Urgent Requests
Work arrives unpredictably.

Conduct code reviews and ensure adherence to best practices and coding standards
Interviewers want to know:
- How you perform code reviews
- What you look for
- How you provide feedback
- How you maintain coding standards
- How you mentor developers
How do you conduct code reviews and ensure adherence to best practices and coding standards?
I treat code reviews as an opportunity to improve code quality, maintainability, security, and team knowledge sharing. During reviews, I focus on correctness, readability, performance, security, test coverage, adherence to coding standards, and alignment with the overall architecture. I provide constructive feedback, explain the reasoning behind my suggestions, and encourage discussions rather than simply approving or rejecting changes. I also ensure that the code follows SOLID principles, clean code practices, and established team guidelines.
What Do You Look For During Code Reviews?
- Code Correctness
- Readability
- SOLID Principles
- Performance
- Exception Handling
- Security
- Test Coverage
What coding standards do you enforce?
- Meaningful naming conventions
- Constructor injection
- SOLID principles
- Clean Code practices
- Proper exception handling
- Logging standards
- Unit test coverage
- Security best practices
- Consistent formatting
- Avoidance of code duplication
What would you do if a developer disagrees with your review comments?
I would discuss the concern openly and focus on the technical reasoning rather than personal preferences. If there are multiple valid approaches, I would evaluate them based on maintainability, performance, consistency, and team standards. If necessary, I would involve the team or architect to reach a consensus.
