10+ UST Software Developer Interview Questions and Answers

Design phase is crucial in software development to plan and visualize the system architecture and functionality.

• Identify the requirements and constraints

• Create a high-level design and break it down into smaller components

• Choose appropriate technologies and tools

• Consider scalability, maintainability, and security

• Iterate and refine the design based on feedback

• Examples: UML diagrams, flowcharts, wireframes

I stands for Interface Segregation Principle in SOLID design principles.

• Interface Segregation Principle states that a client should not be forced to depend on methods it does not use.

• It promotes the use of smaller, cohesive interfaces instead of large, monolithic ones.

• This helps in reducing the coupling between different components of the system.

• For example, if a class needs only a subset of methods from an interface, it should not be forced to implement all the methods.

Use JCL to extract 5th row from a PS file

• Use the SORT utility in JCL to extract the 5th row from the PS file

• Specify the starting position and length of the record in the SORT statement

• Use the OUTFIL statement to write the extracted row to an output file

The application uses OAuth 2.0 for authentication and role-based access control for authorisation.

• OAuth 2.0 is an industry-standard protocol for authorisation and authentication.

• Role-based access control restricts access based on the user's role.

• Examples of roles include admin, user, and guest.

• OAuth 2.0 allows users to grant access to their resources without sharing their credentials.

• The application may also use multi-factor authentication for added security.

Spark launches job on Yarn by creating an application master and containers for executors.

• Spark submits a job to Yarn ResourceManager

• Yarn launches an ApplicationMaster on a NodeManager

• ApplicationMaster requests containers for executors from ResourceManager

• Containers are launched on NodeManagers

• Executors run tasks on data partitions

• Results are returned to the driver program

Communication between components is achieved through various methods like props, events, and state management.

• Use props to pass data from parent to child components

• Use events to trigger actions in one component from another

• Use state management libraries like Redux or Vuex for global state management

MapReduce is a programming model used to process large datasets in parallel on a Hadoop cluster.

• MapReduce breaks down the input data into smaller chunks and processes them in parallel.

• It consists of two phases: Map phase and Reduce phase.

• Map phase processes the input data and produces intermediate key-value pairs.

• Reduce phase takes the output of Map phase and combines the values with the same key.

• Examples of MapReduce applications include word count, log analysis, and recomme...read more

Generative AI is a type of artificial intelligence that is capable of creating new content, such as images, text, or music, based on patterns and examples it has been trained on.

• Generative AI uses neural networks to generate new content based on patterns in existing data.

• Examples of generative AI include DeepDream, which creates surreal images, and GPT-3, a language model that can generate human-like text.

• Generative AI can be used in various fields such as art, music, and wri...read more

Use regular expressions to extract numbers from a string.

• Use regex pattern '\d+' to match one or more digits in the string.

• Use a loop to iterate through the matches and store them in an array.

• Consider using a library like 're' in Python for easier implementation.

Session management techniques are used to maintain user sessions and prevent unauthorized access.

• Session IDs and cookies are commonly used to manage sessions.

• Session timeouts can be set to automatically log out inactive users.

• Secure session management practices should be followed to prevent session hijacking.

• Session data should be encrypted and stored securely.

• Regular session audits should be conducted to identify and address vulnerabilities.
