Goldman Sachs

Hello everyone, just went through GS Superday. Here are the details: 1 - SDLC + Resume round: The questions from my resume were relatively easy, just some deep dives. They asked me a LC question in this round: avgOfStudentsScore(). You should be able to find it easily. We had around 10 mins remaining in this round, so the interviewers asked me to verbally solve Parking Lot (multiple floors) question. I still wrote down the class design to be safe 2 - Design Round: I was expecting LLD but was asked HLD for twitter and only tweets on home page (global tweets + follower tweets). Asked to draw a diagram. After this, I was asking to write down the entities and their fields. Then the interviewers asked me a bunch of questions about databases: difference between relational databases vs others, why postgreSQL here, can we use any other database, etc. Then they asked me to exolain how OOP principles would apply here (specificially in data entities). Overall, not too hard if you study System Design and solve frequently asked questions from GS. 3 - DSA: This is the round where I struggled a bit. I was asked to design a blackjack game where the Ace could be used as 1 or 11. Tell us if a hand is blackjack or not. I struggled with the egde case part. 2 days after this, I was invited to an additional DSA round. I think probably because feedback from all rounds (Coderpad + Design + SDLC) was really good - only DSA wasn't good. Additional DSA round: Max area of 1s in a grid with 0s and 1s. Classic leetcode question. They grilled me hard on this one though. 10-20 questions about DFS vs BFS were asked. Waiting for results - USA #Goldman #GoldmanSachs
