Goldman Sachs Interview Experience 💼 | 5 Rounds + DSA, LLD & Java Questions

Goldman Sachs SDE Interview Experience 💼 | 5 Rounds, DSA, LLD & Java Questions ⚠️ Disclaimer: This is my personal interview experience. The exact interview process and questions can vary depending on the role, team, location, experience level, and interviewer. ━━━━━━━━━━━━━━━━━━ 📌 INTERVIEW PROCESS ━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━━━━━━━ 🔹 ROUND 1 — DSA / Problem Solving ━━━━━━━━━━━━━━━━━━ 💡 Question 1: Highest Average Student Given student marks across different subjects, where a student can take one or multiple exams, find the student who has the **highest average score**. 💡 Question 2: Shortest Path Between Two Stations Given a network of stations where the stations are represented by **names instead of numbers**, find the shortest path between Station A and Station B. Every edge has a weight of 1. ━━━━━━━━━━━━━━━━━━ 🔹 ROUND 2 — DSA + Greedy ━━━━━━━━━━━━━━━━━━ 💡 Question 1: Rotten Oranges A classic *Rotten Oranges / BFS* problem. The interviewer also focused on how I approached the problem, complexity, and implementation. 💡 Question 2: Jump Across the Array You are given an array where the value at an index tells you how far you can jump from that position. The question was essentially: ━━━━━━━━━━━━━━━━━━ 🔹 ROUND 3 — Resume + Java + LLD / Design ━━━━━━━━━━━━━━━━━━ This round moved beyond DSA and focused heavily on software engineering fundamentals. Topics discussed: ☑️ Resume & Project Discussion ☑️ Spring vs Spring Boot ☑️ Software Development Life Cycle (SDLC) ━━━━━━━━━━━━━━━━━━ 🔹 ROUND 4 — LLD / Design ━━━━━━━━━━━━━━━━━━ ☑️ Design Patterns One of the design questions was: You have a system that needs to: ➡️ Fetch data ➡️ Generate a report The data source could be: • API • File • Database And the report could be: • PDF • CSV • HTML The question was: 👉 How would you design this system? 👉 Which design patterns would you use? 👉 How would you make the system extensible? 💡 Question 2: Design a Wallet Another High-Level Design question was to design a **Wallet system**. ━━━━━━━━━━━━━━━━━━ 🔹 ROUND 5 — Advanced Java + DSA + Code Quality ━━━━━━━━━━━━━━━━━━ This was one of the most interesting rounds. 💡 Question 1: O(1) Push & Fetch Given elements, design a data structure where: 👉 Push = O(1) 👉 Fetch = O(1) There was also a requirement around maintaining a consistent ordering during push/fetch operations. This tests your ability to combine multiple data structures and reason about complexity guarantees. 💡 Question 2: Code Quality & Testing The discussion also covered: • Code quality • Testing • JVM internals 💡 Question 3: Implement HashCode & Equals I was asked to explain/implement: 👉 equals() 👉 hashCode() and understand why their contract matters when using objects in Java collections. 💡 Question 4: Implement HashMap Internally Another discussion focused on how a *HashMap works internally* and how you would implement one. Topics include: • Hashing • Buckets • Collision handling • Key-value storage • equals() and hashCode() • Time complexity ━━━━━━━━━━━━━━━━━━ 🔗 RELATED PROBLEMS ━━━━━━━━━━━━━━━━━━ LeetCode / coding practice links will be added here for the problems discussed in the video.
