Kiya.ai Interview Questions and Answers

Improve legacy app performance by optimizing code, implementing caching, and scaling resources.

• Optimize code by identifying and removing bottlenecks

• Implement caching to reduce database calls and improve response time

• Scale resources by using containers or serverless architecture

• Use asynchronous processing for long-running tasks

• Upgrade hardware or infrastructure if necessary

Design a user access control system with granular control for pages, controls, data, and response masking.

• Implement role-based access control (RBAC) to assign permissions to users based on their roles.

• Utilize attribute-based access control (ABAC) for more fine-grained control over access to specific pages, controls, and data.

• Implement data masking techniques to ensure sensitive information is not exposed in responses.

• Use a combination of authentication mechanisms such as OAut...read more

Microservices architecture for a wealth management app involves breaking down the application into smaller, independent services.

• Each microservice focuses on a specific business function, such as client onboarding, portfolio management, or reporting.

• Services communicate through APIs, allowing for flexibility and scalability.

• Each microservice can be developed, deployed, and scaled independently, leading to faster development cycles and easier maintenance.

• Microservices architec...read more

Optimizing sparse array access involves using data structures like hash maps or trees to efficiently store and retrieve values.

• Use a hash map to store only non-null values and their corresponding indices.

• Implement a tree-based data structure like a binary search tree or a trie for faster access to sparse array elements.

• Consider using a compressed sparse row (CSR) format for large sparse arrays to reduce memory usage and improve access times.

Non functional requirements are criteria that specify how a system should behave, rather than what it should do.

• Performance - system should respond within 2 seconds for all user interactions

• Scalability - system should be able to handle 1000 concurrent users

• Reliability - system should have a 99.99% uptime

• Security - system should encrypt all sensitive data

• Usability - system should have a user-friendly interface
