R Systems International Senior Software Engineer Interview Questions and Answers for Freshers

Frameworks provide structure and pre-built components for software development, but can also limit flexibility and require learning curve.

• Advantage: Provides structure and pre-built components for faster development

• Advantage: Can improve code quality and maintainability

• Disadvantage: Can limit flexibility and customization

• Disadvantage: Requires learning curve and potential dependency issues

• Example: ReactJS provides a fr...read more

Oops stands for Object-Oriented Programming. It is a programming paradigm that uses objects to represent real-world entities.

• Advantages: code reusability, modularity, encapsulation, inheritance, polymorphism

• Disadvantages: complexity, steep learning curve, performance overhead

• Example: creating a class 'Car' with properties like 'make', 'model', and 'year', and methods like 'start_engine' and 'stop_engine'

Map and unordered_map are associative containers that store elements in key-value pairs.

• Map is implemented as a balanced binary tree while unordered_map is implemented as a hash table.

• Map stores elements in sorted order based on the key while unordered_map does not guarantee any specific order.

• Map has a slower insertion and deletion time complexity than unordered_map.

• Map is useful when we need to maintain elements in a...read more

Sort array of strings based on frequency of digits in each element.

• Create a dictionary to store frequency of digits in each element.

• Sort the array based on the frequency of digits using the dictionary.

• Handle ties by sorting based on the original order of elements.

Check if a string is a palindrome

• Iterate through each string in the array

• For each string, compare characters from start and end to check if it's a palindrome

• Return true if all strings are palindromes, false otherwise

Various automation frameworks like keyword-driven, data-driven, hybrid, and behavior-driven are commonly used in software testing.

• Keyword-driven framework: Tests are written using keywords and actions.

• Data-driven framework: Tests are driven by data sets.

• Hybrid framework: Combination of multiple frameworks.

• Behavior-driven framework: Focuses on behavior of the system.

• Page Object Model (POM): Organizes code by separating

Distributed systems are a network of independent computers that work together to achieve a common goal. Security can be maintained through encryption, authentication, access control, and monitoring.

• Distributed systems consist of multiple computers that communicate and coordinate actions to achieve a common goal.

• Security in distributed systems can be maintained through encryption of data in transit and at rest.

• Authentic...read more

Container orchestration tools are crucial for managing the deployment, scaling, and monitoring of large complex systems.

• Container orchestration tools help automate the deployment and scaling of containerized applications, making it easier to manage large complex systems.

• They provide features like service discovery, load balancing, health checks, and auto-scaling, which are essential for ensuring high availability and p...read more
