WiseTech Global Interview Questions and Answers

For my academic project, I designed a low-level system for a file management application.

• Identified the requirements and constraints of the system

• Designed the file structure and organization

• Implemented file operations such as create, read, write, and delete

• Optimized the system for performance and scalability

• Tested the system thoroughly to ensure functionality and reliability

Test driven environment is a software development approach where tests are written before the actual code.

• Tests are written before the code is developed

• Code is developed to pass the tests

• Advantages include better code quality, faster development, and easier maintenance

• Reduces the risk of bugs and errors

• Helps in identifying issues early in the development cycle

Design patterns are reusable solutions to common software design problems.

• Design patterns provide a common language for developers to communicate about software design.

• They can improve code quality, maintainability, and scalability.

• Examples of design patterns include Singleton, Factory, and Observer.

• Implementation involves applying the pattern to a specific problem in a software system.

• Design patterns can be implemented in various programming languages and frameworks.

SOLID principles are a set of guidelines for writing maintainable and scalable code.

• Single Responsibility Principle: A class should have only one reason to change.

• Open/Closed Principle: A class should be open for extension but closed for modification.

• Liskov Substitution Principle: Subtypes should be substitutable for their base types.

• Interface Segregation Principle: Clients should not be forced to depend on interfaces they do not use.

• Dependency Inversion Principle: High-level...read more
