The Ultimate Guide to Cracking Goldman Sachs CoderPad Interview Questions

If you’re aiming for a software engineering role at Goldman Sachs, the CoderPad round is a crucial step in the interview process. This online coding assessment is designed to evaluate your problem-solving skills and ability to write clean, efficient code. To help you prepare for this challenging round, we’ve compiled a comprehensive guide covering everything you need to know about Goldman Sachs CoderPad interview questions.

Understanding the CoderPad Round

The CoderPad round typically occurs after the initial online screening test. During this round, you’ll be presented with one or two coding problems that you’ll need to solve within a specified time limit, usually around an hour. The interviewer will share their screen with you, and you’ll be asked to write and run your code in a collaborative coding environment.

The problems you’ll encounter in this round are focused on testing your knowledge of data structures and algorithms. You may be asked to implement various data structures, such as linked lists, trees, or hash tables, or to solve algorithmic problems involving sorting, searching, or dynamic programming.

Common Goldman Sachs CoderPad Interview Questions

To give you an idea of the types of questions you might encounter, here are some examples of common Goldman Sachs CoderPad interview questions:

Data Structures

  • Implement a singly linked list and its basic operations (insert, delete, search).
  • Implement a binary search tree and its basic operations (insert, delete, search).
  • Implement a hash table with separate chaining for collision resolution.
  • Implement a queue using two stacks.
  • Implement a stack using a singly linked list.


  • Write a function to find the nth Fibonacci number.
  • Implement merge sort algorithm for sorting an array.
  • Write a function to find the longest common subsequence of two strings.
  • Implement the Dijkstra algorithm to find the shortest path between two nodes in a weighted graph.
  • Write a function to find the maximum subarray sum in an array.


  • Given an array of integers, find the pair of elements whose sum is closest to a given target value.
  • Given a string, find the longest palindromic substring.
  • Implement a function to validate if a given binary tree is a binary search tree (BST).
  • Given a matrix, find the maximum sum of any submatrix.
  • Implement a function to find the kth smallest element in an unsorted array.

Preparing for the CoderPad Round

To excel in the CoderPad round, it’s essential to have a solid understanding of data structures and algorithms. Here are some tips to help you prepare:

  1. Review Data Structures and Algorithms: Refresh your knowledge of fundamental data structures (arrays, linked lists, trees, graphs, hash tables) and algorithms (sorting, searching, dynamic programming, recursion). Practice implementing these data structures and solving algorithmic problems on platforms like LeetCode or HackerRank.

  2. Practice Coding: Coding skills are crucial in the CoderPad round. Practice writing clean, efficient code in your preferred programming language. Familiarize yourself with the language’s syntax, standard library, and common algorithms.

  3. Understand Time and Space Complexity: Be prepared to analyze the time and space complexity of your solutions. Interviewers may ask you to optimize your code for better performance or to discuss trade-offs between different approaches.

  4. Mock Interviews: Participate in mock interviews or coding sessions with friends or online communities. This will help you get comfortable with the interview setting and improve your problem-solving skills under time pressure.

  5. Brush up on Coding Basics: Review basic coding concepts like loops, conditionals, recursion, and data manipulation. These fundamental skills are essential for solving coding problems effectively.

  6. Communicate Clearly: During the CoderPad round, you’ll be expected to communicate your thought process and explain your code. Practice verbalizing your approach and be prepared to ask clarifying questions if needed.

Additional Tips and Resources

To further enhance your preparation, consider the following tips and resources:

  • Familiarize yourself with the CoderPad platform by trying out the free demo or practicing on similar collaborative coding environments.
  • Check out resources like “Cracking the Coding Interview” by Gayle Laakmann McDowell or “Introduction to Algorithms” by Thomas H. Cormen for in-depth explanations and practice problems.
  • Participate in coding competitions or join online communities like LeetCode Discuss to learn from others and stay up-to-date with the latest problem-solving techniques.
  • Consider enrolling in an interview preparation program or bootcamp specifically designed for tech interviews, as they provide structured guidance and personalized feedback.

Remember, cracking the Goldman Sachs CoderPad interview questions requires a combination of technical expertise, problem-solving skills, and practice. By dedicating time and effort to preparation, you’ll increase your chances of impressing the interviewers and securing your dream job at Goldman Sachs.
