Goldman Sachs Quant Summer Analyst Internship Interview Experience 2025
Third year CS student at a university in the US. Already had an internship locked in but GS came to campus so I figured why not. Sharing the full breakdown.
The process was an online assessment, then two technical rounds and an HR round, all in one day. Pay was basically equivalent to a ~$10k/month US tech internship for 2 months.
Around 800 students took the HackerRank test. Three DSA problems, 15-20 aptitude questions, and one descriptive self-story question. You needed 2/3 DSA problems solved plus solid aptitude to move on. Both sections share the same timer so you're basically speed-running your own panic attack. 44 made it through and I was one of them.
First technical round started with a self-intro then straight into projects. DSA covered Merge Sort vs Quick Sort tradeoffs, writing Merge Sort on paper with a full recursion tree diagram, then Floyd's Cycle Detection on linked lists. Basic SQL and light OS questions to finish. 20 students moved on and I cleared it.
Second technical round went back to the project briefly then into security concepts. JWT questions were all scenario-driven, things like "someone steals the access token, now what." Reciting the definition of JWT is not going to save you here. Then the interviewer asked my strongest DSA topic. I said linked lists. Question was reverse a linked list in groups of K, full working code on paper, 10 minutes. Did not finish. 13 students cleared. I was not one of them.
HR round went to 8 students who got the offer.
Happy to answer any questions if you're going through a similar process.
