Interview Preparation Tips
Experience: Though technical questions were not that difficult but the quant section was way too hard and almost impossible to solve completely in given time limit.
Tips: It’s better if you attempt less questions (in quant) but do them right (I attempted less than 40% quant and still got through).
Round: Technical Interview
Experience: Next they would have 2-3 technical rounds where they cover most of the areas of CS. Some of the areas where they concentrated more would be Algorithms, OOPS Concepts and Logical Puzzles.
Tips: Brush up important concepts from various areas such as Operating System, OOPS, Software Engineering. Be ready for some really challenging questions in Algorithms. Also they do ask quite a few logical puzzles so it’s important you practice a lot of them online before the interview.
General Tips: D E Shaw selects very few candidates + comes in starting weeks of placement season, so competition is immense. Multiple companies come on same day, so it becomes a little tedious. Surely I wasn't the better candidate that day.
Skill Tips: D E Shaw focuses more on your ability to solve logical problems, so make sure you are in best state of your mind and speak while solving any problem because what they are looking for is not the right answer (well of course they are) but also how are you approaching the problem.

A binary tree is a data structure where each parent node has at most two children.
The mirror ...
- Ans.
Convert a binary tree into its mirror tree by interchanging left and right children of non-leaf nodes.
Traverse the binary tree in postorder fashion and swap the left and right children of each non-leaf node.
Use recursion to solve the problem efficiently.
Remember to handle null child nodes represented by -1 in the input.
- Q2.
Maximum Sum Subarray Problem Statement
Given an array of integers, find the maximum sum of any contiguous subarray within the array.

- Ans.
Find the maximum sum of any contiguous subarray within an array in O(N) time complexity.
Iterate through the array and keep track of the maximum sum of subarrays encountered so far
At each index, decide whether to include the current element in the subarray or start a new subarray
Update the maximum sum if a new maximum is found
Example: For array [34, -50, 42, 14, -5, 86], the maximum sum subarray is [42, 14, -5, 86] with

Interview Preparation Tips
Experience: The first round had two sections. First section consisted of general aptitude and technical aptitude questions. In the second section we were given one coding question, for which we had to write the code in a language of our preference (C,C++,Java). Around 20 students were selected in the first round.
Round: Technical Interview
Experience: The second round was a technical interview. Two interviewers were present and the interview duration was 1-1.5 hours. Questions on Computer Networks, Databases, Operating Systems, Algorithms were asked. But they were more concerned about coding fundamentals especially C++ and Java. 6 students were selected in the second round.
Round: Technical Interview
Experience: Third round was again a technical interview. The interview process was same as previous second round.
Round: HR Interview
Experience: All the 6 students who were selected for the third round had a HR interview.
General Tips: The technical interview process was exhausting as the interview duration was 1-1.5 hours and challenging as they asked questions from all major fields of computer science.
