🚀 System Design Prep ends here 🚀 🚨 I have cleared most of the system design interview rounds with this guide When it comes to System Design Interviews, there’s a lot of material out there… But trust me, you don’t need to drown yourself in 100s of resources. 👉 This one PDF is all you need to build a rock-solid foundation. 👉 I personally used it and cleared most of my system design rounds with just this. 👉 It covers the fundamentals + real-world architectures in a clear, structured way. 📌 Inside you’ll find: ➡️ Basics of scalability (Load balancers, Caching, Databases) ➡️ Deep dives into core components (Queues, Consistent Hashing, CAP theorem) ➡️ End-to-end architectures (URL shortener, Instagram, WhatsApp, etc.) ➡️ Tradeoffs explained in simple language 💡 Remember: In interviews, it’s not about fancy terms — it’s about clarity of thought, structured approach, and knowing trade-offs. This PDF helps you nail exactly that. 🔥 If you’re starting your System Design prep, this could be your one-stop guide. #systemdesign #interviewprep #softwareengineering #growth #careerdevelopment #google #microsoft

Solve these 12 Groups of 55+ Graph Problems to crack & solve mostly any Graph problem designed for SDE Interviews. I wish I had this cheatsheet back when I was first switching from Amazon and brushing up on all my DSA basics.  Group  𝟭 – DFS/BFS Traversal - Keys and Rooms - Number of Provinces - Reorder Routes to Make All Paths Lead to the City Zero - Round Trip - Word Ladder - Valid BFS? - Minimum Number of Operations to Make X and Y Equal - Clone Graph  Group  𝟮 – Cycle Detection - Detect Cycle in an Undirected Graph - Detect Cycle in a Directed Graph - Check if a Graph Has a Cycle of Odd Length - Detect Cycles in 2D Grid - Shortest Cycle in a Graph  Group  𝟯 – Topological Sort & Order - Course Schedule II - Find Eventual Safe States - All Ancestors of a Node in a Directed Acyclic Graph - Alien Dictionary - Largest Color Value in a Directed Graph - Parallel Courses III  Group  𝟰 – Flood Fill & Grids - Flood Fill - Number of Islands - Count Sub Islands - Find All Groups of Farmland - Rotting Oranges - Number of Enclaves - Surrounded Regions - Number of Closed Islands - 01 Matrix  Group  𝟱 – Shortest Path - Network Delay Time - Number of Ways to Arrive at Destination - Minimum Cost to Make at Least One Valid Path in a Grid - Shortest Path in Binary Matrix - Second Minimum Time to Reach Destination  Group  𝟲 – Advanced Graph Patterns - Find the City With the Smallest Number of Neighbors at a Threshold Distance - Minimum Cost to Convert String I - Number of Possible Sets of Closing Branches  Group  𝟕 – Disjoint Set / Union Find - Accounts Merge - Find Latest Group of Size M - GCD Sort of an Array - Checking Existence of Edge Length Limited Paths  Group  𝟴 – Minimum Spanning Tree (MST) - Prim’s Minimum Spanning Tree - Kruskal’s Minimum Spanning Tree - Water Connection Problem - Find Critical and Pseudo-Critical Edges in MST  Group  𝟵 – Network Robustness & Articulation - Articulation Points (Cut Vertices) - Strongly Connected Components - Critical Connections in a Network  Group  𝟭𝟬 – Graph Coloring - Building Teams  - CSES - Is Graph Bipartite? - Check if a Graph Has a Cycle of Odd Length - Valid BFS? - Largest Color Value in a Directed Graph  Group  𝟭𝟭 – Grid-Based Advanced - Detect Cycles in 2D Grid - Find All Groups of Farmland - Number of Closed Islands - 01 Matrix  Group  𝟭𝟮 – Scheduling & Dependencies - Course Schedule II - Parallel Courses III - All Ancestors of a Node in a Directed Acyclic Graph - Alien Dictionary - Find Eventual Safe States
