Tip 1: Do mock interviews with your friends, mentors, or even in front of the mirror. Questions you are sure of may suddenly leave you at a loss during the actual interview.
Tip 2: Practice all the basic programming algorithms and repeated questions. Coding Ninjas' courses are a good place to start.
Tip 3: Practice solving programs in a limited timeframe. You get only 45 minutes in the interview!
Tip 1: Make your resume short, try to limit it to one page, and mention all the skills in which you are confident.



1) A subarray is a part of the array which is contiguous (i.e. elements in the original array occupy consecutive positions) and inherently maintains the order of elements. For example, the subarrays of the array {1, 2, 3} are {1}, {1, 2}, {1, 2, 3}, {2}, {2, 3}, and {3}.
2) Bitwise OR operation takes two numbers and performs OR operation on every bit of those two numbers. For example, consider two numbers 2 and 3 their bitwise OR will be 3. Because the binary representation of 2 is 10 and the binary representation of 3 is 11. And OR of 10 and 11 will be 11 which evaluates to 3.
3) The array may contain duplicate elements.
I maintained two arrays: one with the normal addition of elements (0 query) and the other with XOR elements (1 query). When the query is 0, I iterate the index pointers of both arrays and add the element to the normal array. When it is 1, I only update the XOR array with the XOR of the query element and the number already present in the XOR array. At the end, I compute the suffix of the XOR array and XOR the suffixes with the normal array. Then, I sort and return the normal array.



Input : 1 -> 2 -> 3 -> 4 -> 'NULL' and 'K' = 2
Output: 1 -> 2 -> 4 -> 'NULL'
Explanation:
After removing the second node from the end, the linked list become 1 -> 2 -> 4 -> 'NULL'.

This was actually a pretty easy question.
Step 1: I provided an intuition of the question and how to approach it.
Step 2: I presented a basic two-pass algorithm, then moved to an efficient one-pass algorithm.
Tip 1: Choose a problem statement that has not been extensively implemented already or that needs significant improvements.
Tip 2: Create a complete pipeline for the problem statement you have selected, starting with why you chose that particular statement and detailing how you will approach the solution and the need for improvement.
Tip 3: Develop a prototype or something that can demonstrate your progress. It will show how confident you are in your approach.
He greeted me first and asked how I was doing. He inquired about my previous round and whether I faced any technical difficulties. Then, he asked me to introduce myself and followed up with some HR-related questions.
Tip 1: I would suggest going through some questions beforehand.
Tip 2: Never say anything that shows your incompetence, e.g., "unable to reallocate" or "I don't know." Never use such words!
Tip 3: Have some instances to support your stance on certain decision questions, e.g., when you have shown a leadership role or led your team, etc.
