It comprised of three sections:Section 1: Aptitude: Questions included were mostly from probability, profit, and loss, and covering most of the syllabus of quantitative aptitude. the questions in this round were of medium-hard difficulty level,Section 2: Computer Science Fundamentals: This section comprised of questions from time complexity, DBMS, and OOPs and also some bug finding questionsSection 3: Coding: This section consisted of three coding questions which were of medium to the hard difficulty level. One of the questions in this section was very tough, and only a few candidates were able to solve it. Hence, students who completed even half of this question were invited for further rounds.Round 3: Technical InterviewThe majority of candidates were eliminated from the previous round, and only a few reached the interview round.The technical interview was conducted on Hackerrank’s CodePair platform. It was an approx 45 minute round that started off with an introduction followed by the following questions.The interviewer first asked me about all the data structures that I was comfortable with, and I was completely honest with him and told him that I was familiar with all the basics as well as some advanced data structures. He then asked me the following questions.Given a number, delete that number from a linked list,: This question seems easy at first, however it was quite tricky as we are not given the head of the LinkedList. I got confused at first because I thought that I had to delete that node, however on reading the question repeatedly I realized that we only have to delete the number.After figuring out what the question asked of me, I explained my approach to the interviewer. He was quite satisfied with it and then asked me to code up the solution and I did.Design a data structure with O(1) delete, insert, get random(): This was a tough question for which I required some hints, and after that, I was able to come up with a solution. This question was then modified by the interviewer with duplicates allowed as well.Internal implementations of the heap, Binary Search Tree: D E Shaw is a company that focuses a lot on in-depth questions from your language. Since my language was Java, I was also asked Java-specific questions such as: Why is the Java platform independent? Declaration of arrays in Java? Memory allocation of arrays in JavaQuestions on searching algorithms.I was asked to list the searching algorithms that I was familiar with and was asked questions around binary search and ternary search.This marked the end of my technical interview after which I got a call that I had cleared the technical interview and was scheduled for an HR interview.After the HR interview, I got an email saying that I was selected and that was the happiest moment of my life. This was all about my experience and GeeksForGeeks helped me a lot in my preparation Journey.Hope this helps!!
