Your biggest enemy 𝐅𝐄𝐀𝐑 𝐨𝐟 𝐑𝐞𝐣𝐞𝐜𝐭𝐢𝐨𝐧 People hesitate to apply for many opportunities just because of fear of rejection. However, not applying means you are automatically rejecting yourself. They usually think I will start applying after 6-8 months with full preparation. Do you really think it will work ??? Interview calls usually take months 😅 My suggestion would be to start applying after 10 days to 1 month of preparation . Try to give as many interviews as you can. In this way, you will learn 👇🏻 🌴 Frequently asked questions 🌴 Interview pattern 🌴 How to tweak your answers? Give a try ,even in the worst scenario, you will get some interview experience. That experience will eventually help you in the future All the best 👍👍

Important Sorting Algorithms- Bubble Sort: Bubble Sort is the most basic sorting algorithm, and it works by repeatedly swapping adjacent elements if they are out of order. Merge Sort: Merge sort is a sorting technique that uses the divide and conquer strategy. Quicksort: Quicksort is a popular sorting algorithm that performs n log n comparisons on average when sorting an array of n elements. It is a more efficient and faster sorting algorithm. Heap Sort: Heap sort works by visualizing the array elements as a special type of complete binary tree known as a heap. Important Searching Algorithms- Binary Search: Binary search employs the divide and conquer strategy, in which a sorted list is divided into two halves and the item is compared to the list’s middle element. If a match is found, the middle element’s location is returned. Breadth-First Search(BFS): Breadth-first search is a graph traversal algorithm that begins at the root node and explores all neighboring nodes. Depth-First Search(DFS): The depth-first search (DFS) algorithm begins with the first node of the graph and proceeds to go deeper and deeper until we find the goal node or node with no children.
