Helm360 ASP.NET Developer Interview Questions and Answers

Interfaces define a contract for classes to implement certain methods and properties.

• Interfaces allow for polymorphism and loose coupling.

• Classes can implement multiple interfaces.

• Interfaces cannot be instantiated on their own.

• Interfaces can have default method implementations.

• Interfaces can be used to enforce design patterns like the adapter pattern.

Main challenges faced in GCP implementation

• Data migration and integration with existing systems

• Ensuring security and compliance with regulations

• Optimizing costs and managing resources effectively

• Training and upskilling employees to use GCP effectively

• Choosing the right services and configurations for specific use cases

Best practices for BigQuery include optimizing queries, managing costs, and securing data.

• Optimize queries by using partitioning, clustering, and caching

• Manage costs by using cost controls, monitoring usage, and optimizing storage

• Secure data by using IAM roles, encryption, and audit logs

C# concepts including abstraction, interface, abstract method, abstract class, polymorphism, encapsulation, inheritance, and serialization.

• Abstraction: hiding implementation details

• Interface: defining a contract for behavior

• Abstract method: method without implementation

• Abstract class: class with one or more abstract methods

• Polymorphism: ability of objects to take on multiple forms

• Encapsulation: bundling data and behavi...read more

Program to print a pattern and implement bubble sort on an array of strings.

• For pattern printing, use nested loops to print the desired pattern.

• For bubble sort, compare adjacent elements and swap if necessary.

• Use a loop to iterate through the array until no more swaps are needed.
