Northern Arc Capital Associate Software Engineer Interview Questions, Process, and Tips

Text data can be loaded into DB systems using various methods such as SQL INSERT statements, bulk loading, or ETL processes.

• Use SQL INSERT statements to insert text data into the database one record at a time.

• For large datasets, consider using bulk loading techniques like BULK INSERT or LOAD DATA INFILE.

• ETL (Extract, Transform, Load) processes can be used to extract text data from different sources, transform it as per...read more

Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.

• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing by providing mock dependencies.

• There are three types of dependency injection: constructor injection, setter injection, and interface injection.

State in React is a JavaScript object that stores data and determines how a component renders and behaves.

• State is mutable and can be updated using the setState() method

• State should be used for data that will change over time and affect the component's rendering

• State should not be modified directly, use setState() instead

OOPS concepts refer to Object-Oriented Programming principles like Inheritance, Encapsulation, Polymorphism, and Abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex implementation detail

Solid concepts are fundamental principles or ideas that are well-established and widely accepted in a particular field.

• Solid concepts provide a strong foundation for further learning and development.

• They are essential for understanding complex topics and solving problems effectively.

• Examples of solid concepts in software engineering include object-oriented programming, design patterns, and data structures.

Code to check if a string is a palindrome or not.

• Iterate through the string from both ends and compare characters.

• Use two pointers, one starting from the beginning and one from the end.

• If characters at both pointers are equal, move both pointers towards the center.

• If characters at any point are not equal, return false.

• If both pointers meet in the middle, return true as the string is a palindrome.
