10+ Fingent Interview Questions and Answers

I handle requests outside scope by evaluating impact, discussing with stakeholders, and proposing solutions.

• Evaluate the impact of the request on the project timeline and budget

• Discuss the request with stakeholders to understand their needs and expectations

• Propose solutions that balance the request with the project's goals and constraints

• Document the decision-making process and communicate it to the team

• Ensure that any changes to scope are approved and documented

A controller is used for handling user requests while an API controller is used for handling API requests.

• A controller is used for rendering views while an API controller is used for returning data in JSON format.

• API controllers are usually lighter and faster than regular controllers.

• API controllers are often used for building RESTful APIs.

• Examples of API frameworks that use API controllers include Laravel and ASP.NET Core.

Overloading is having multiple methods with the same name but different parameters. Overriding is implementing a method in a derived class with the same name and signature as in the base class.

• Overloading allows a class to have multiple methods with the same name but different parameters.

• Overriding allows a derived class to provide a different implementation of a method that is already defined in the base class.

• Overloading is resolved at compile-time based on the number, type...read more

Strict mode is a way to write secure and optimized JavaScript code.

• Enables catching of silent errors

• Disallows duplicate property names or parameters

• Prevents use of undeclared variables

• Makes `eval()` safer to use

• Throws errors on invalid usage of `this` keyword

The ref and out keywords are used in C# to pass arguments by reference instead of by value.

• The ref keyword is used to pass a variable by reference, allowing the called method to modify the value of the variable.

• The out keyword is similar to ref, but it is used when the called method needs to assign a value to the variable being passed.

• The ref keyword requires the variable to be initialized before passing it to the method, while the out keyword does not.

• Both ref and out parame...read more

SQL join queries are used to combine rows from two or more tables based on a related column between them.

• Join queries are used to retrieve data from multiple tables in a single query.

• Common types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN.

• Join conditions are specified using the ON keyword, which defines the column(s) to join on.

• Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column;

ADO .NET database calling steps involve establishing a connection, creating a command object, executing the command, and handling the results.

• Establish a connection to the database using a connection string

• Create a command object to specify the SQL query or stored procedure to be executed

• Execute the command to retrieve or modify data in the database

• Handle the results by reading data from a DataReader or updating data using a DataAdapter

Yield keyword is used in Python to create generators that can be used to iterate over large datasets without loading them into memory.

• Yield is used to pause and resume a function's execution.

• Generators created using yield are memory efficient as they only load data when needed.

• Yield can be used to implement lazy evaluation.

• Yield can be used to create infinite sequences.

• Example: def my_generator(): yield 1; yield 2; yield 3;

• Example: for num in my_generator(): print(num)

• Example...read more

Building rapport with clients requires active listening, empathy, and clear communication.

• Listen actively to their needs and concerns

• Show empathy by acknowledging their feelings and perspectives

• Communicate clearly and transparently about expectations and progress

• Find common ground and shared interests to establish a connection

• Be respectful and professional in all interactions

OOPs concepts are fundamental principles in object-oriented programming, including 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 details and showing only the necessary features.

The triple constraints of my projects are time, cost, and scope.

• Time: The project must be completed within a specific timeframe.

• Cost: The project must be completed within a specific budget.

• Scope: The project must meet the specific requirements and objectives.

• Changes to one constraint may affect the others.

• Example: If the scope of the project is increased, the time and cost may also increase.

IEnumerable is read-only and forward-only while IQueryable is queryable and can be used with LINQ to SQL.

• IEnumerable is used for in-memory collections while IQueryable is used for querying external data sources.

• IQueryable allows for deferred execution while IEnumerable does not.

• IQueryable can be used with LINQ to SQL to translate queries into SQL statements.

• IEnumerable is simpler and more lightweight than IQueryable.

• IEnumerable is implemented by List, Array, Dictionary, etc. ...read more

useEffect is a hook in React that allows you to perform side effects in functional components.

• useEffect is used to manage component lifecycle in functional components.

• It takes two arguments: a function that performs the side effect and an array of dependencies.

• The function passed to useEffect is called after every render.

• The array of dependencies is used to determine when the effect should be re-run.

• If the array is empty, the effect will only run once on mount and unmount.

• use...read more

React has three main phases in its lifecycle: mounting, updating, and unmounting.

• Mounting: when a component is created and inserted into the DOM

• Updating: when a component is updated due to changes in props or state

• Unmounting: when a component is removed from the DOM

• Lifecycle methods can be used to perform actions at each phase, such as componentDidMount() or componentWillUnmount()

• React also has error handling methods, such as componentDidCatch()

Action filters are used in ASP.NET MVC to execute code before or after an action method is called.

• Action filters can be used to perform authentication and authorization checks.

• They can also be used to modify the result of an action method.

• Examples of action filters include Authorize, OutputCache, and HandleError.

• Action filters can be applied globally, to a controller, or to an individual action method.

A promise is an object representing the eventual completion or failure of an asynchronous operation.

• Promises are used to handle asynchronous operations such as fetching data from a server.

• They provide a cleaner alternative to callbacks.

• Promises have three states: pending, fulfilled, and rejected.

• They can be chained together using .then() and .catch() methods.

• Promises can also be used with async/await syntax.
