Fynd Interview Questions, Process, and Tips

I will showcase my projects from oldest to newest, displaying only the final outcomes.

• Start with the earliest project and work your way to the most recent one

• Focus on showcasing the final deliverables or outcomes of each project

• Provide a brief overview or context for each project if necessary

SQL is a relational database management system, while NoSQL is a non-relational database management system.

• SQL uses structured query language for querying data

• NoSQL databases are more flexible and can handle unstructured data

• SQL databases are vertically scalable, while NoSQL databases are horizontally scalable

• Examples of SQL databases include MySQL, Oracle, and SQL Server

Use a loop to send 1000 API requests

• Create a loop that iterates 1000 times

• Inside the loop, make a request to the API endpoint

Event loop is a mechanism that allows for asynchronous programming by handling and executing events in a loop.

• Event loop is a part of the runtime environment that continuously checks the event queue and executes the callback functions associated with those events.

• It allows for non-blocking I/O operations, making it possible to handle multiple events concurrently.

• Event loop is commonly used in JavaScript for handling as...read more

Virtual DOM is a lightweight copy of the actual DOM in memory, used for efficient updates and rendering in web development.

• Virtual DOM is a concept used in frameworks like React to improve performance by minimizing actual DOM manipulations.

• When changes are made to the virtual DOM, a diffing algorithm compares it with the actual DOM and only updates the necessary parts.

• This helps in reducing the number of updates needed...read more

Event loop in JavaScript manages asynchronous operations by executing callback functions in a queue.

• Event loop is responsible for handling asynchronous operations in JavaScript.

• It continuously checks the call stack for any pending tasks and executes them in order.

• Event loop ensures that the code runs efficiently without blocking the main thread.

• Example: setTimeout function in JavaScript uses the event loop to execute a

Prototypes in JavaScript are used to add new properties or methods to existing objects.

• Prototypes allow for inheritance in JavaScript.

• All objects in JavaScript are linked to a prototype object.

• Modifying the prototype object affects all instances of that object type.

Prototype for array.filter function to filter array of strings

• Use Array.prototype.filter method to iterate through the array

• Pass a callback function to filter out elements based on a condition

• Return a new array with filtered elements

Python code to find the factorial of a number

• Use a recursive function to calculate the factorial

• Handle edge cases like 0 and negative numbers

• Factorial of a number n is the product of all positive integers less than or equal to n
