Goldman Sachs – SRE / Python Coding Interview Experience Round Structure: * ~40 mins coding round * ~20 mins resume/project discussion Coding round had 2 questions, roughly 20 mins each. Question 1: Find the first non-repeating character in a string. Started with brief brute force discussion: Then moved to optimized hashmap approach: Question 2: Dynamic Programming / Matrix traversal problem: - rock collector Find optimal path in grid while moving only in allowed directions (up/right). Started with brief brute force explanation- Then moved to DP solution: Interview Style: Interviewer was friendly, collaborative, and helpful throughout the round. She allowed debugging and discussion instead of immediately moving on after mistakes. The round focused more on: * thought process * debugging ability * implementation discipline * explaining tradeoffs * edge case handling Resume Discussion (~20 mins): Questions were mainly around: * llm integration * Kubernetes * observability Overall difficulty: Medium-level algorithms, but implementation accuracy and communication mattered a lot.
