CSG International Interview Questions, Process, and Tips

WCF (Windows Communication Foundation) life cycle involves creation, opening, closing, and disposing of communication objects.

• Creation: Communication objects are created using constructors.

• Opening: Objects are opened to establish communication channels.

• Closing: Communication channels are closed after use.

• Disposing: Objects are disposed to release resources.

• Example: Creating a WCF service involves defining service contr...read more

Core elements of WCF include contracts, services, messages, and endpoints.

• Contracts define what the service does and how clients can interact with it

• Services implement the functionality defined in contracts

• Messages are the data exchanged between clients and services

• Endpoints define the address, binding, and contract for a service

Web API and WCF have different use cases and technologies, each with its own strengths and weaknesses.

• Web API is more lightweight and suitable for building RESTful services, while WCF is more heavyweight and supports various communication protocols.

• Web API is easier to use for building HTTP services, while WCF offers more flexibility and features for building distributed applications.

• Web API is preferred for modern web...read more

Yes, I have used logging extensively in my projects to track application behavior and troubleshoot issues.

• Used logging frameworks like Log4j or SLF4J to log information, warnings, and errors

• Configured log levels to control the amount of detail in logs

• Logged important events, exceptions, and user actions for debugging purposes

• Stored logs in files or databases for future reference

SQL views are virtual tables that display data from one or more tables based on a predefined query.

• SQL views are saved queries that can be used to simplify complex queries.

• They can be used to hide the complexity of underlying tables from users.

• Views can also be used to restrict access to certain columns or rows of a table.

• Changes made to the underlying tables are reflected in the views.

• Example: CREATE VIEW vw_employee

Constraints in SQL are rules and restrictions that are applied to columns in a table to ensure data integrity and consistency.

• Constraints ensure data accuracy and consistency in a database

• Common constraints include NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY, CHECK, and DEFAULT

• NOT NULL constraint ensures a column cannot have a NULL value

• UNIQUE constraint ensures all values in a column are unique

• PRIMARY KEY constraint un...read more

Conflicts in Git are resolved by merging changes, rebasing, or using tools like Git GUI or GitKraken.

• Merge conflicting branches using 'git merge' command

• Rebase conflicting branches using 'git rebase' command

• Use tools like Git GUI or GitKraken to visually resolve conflicts

• Manually edit files to resolve conflicts

• Use 'git status' and 'git diff' to identify conflicting files

OOPs concept is a programming paradigm that focuses on objects and classes to organize code and promote reusability.

• OOPs stands for Object-Oriented Programming

• It involves concepts like inheritance, encapsulation, polymorphism, and abstraction

• Classes are blueprints for objects, which have attributes and methods

• Objects are instances of classes that can interact with each other

• Example: A project using OOPs may have classe...read more

Cucumber is a testing framework that supports Behavior Driven Development (BDD) by allowing tests to be written in plain language.

• Cucumber uses Gherkin syntax to define test cases in a human-readable format

• It allows collaboration between technical and non-technical team members

• Cucumber integrates with various programming languages like Java, Ruby, etc.

• It promotes reusability of code through feature files and step defin
