These are designed to test if you can walk the coding walk and talk the coding talk. You might need to whip up code snippets, discover blunders in someone else’s code, or streamline algorithms.
Expect quizzes on languages like Java, Python, C++, or JavaScript, with topics ranging from juggling strings and arrays to unwinding recursion and untangling sorting algorithms. Here’s what candidates often run into:
| Question | Description |
|---|---|
| Reverse a String | Whip up a function that flips a string back-to-front without cheating (i.e., no built-in functions). |
| Find the Missing Number | Given an array with numbers from 0 to n, find the one that’s playing hooky. |
| Implement a Stack | Build a stack that can handle push, pop, and peek operations like a pro. |
To nail these, roll up your sleeves and dive into coding exercises, get cozy with time-space shenanigans, and master the core algorithms and data structures.
Algorithm and Data Structure Questions
These bad boys dig into how well you can tackle complex challenges. They ask: “Can you design algorithms, size up time and space issues, and make them slicker?”
Common topics involve sorting and searching algorithms, graph outings, dynamic strategies, and playing around with trees. Check out a few examples you might tangle with:
| Question | Description |
|---|---|
| Longest Substring Without Repeating Characters | Hunt down the length of the longest substring minus any character copycats. |
| Binary Tree Maximum Path Sum | Scour a binary tree to find the max loot you can scoop between any two nodes. |
| Detect Cycle in a Directed Graph | Craft a function to sniff out cycles in a directed graph using depth-first search (DFS). |
To come out swinging, ensure you nail core algorithms, practice your problem-solving game, and get comfy with arrays, linked lists, trees, and graphs.
System Design Questions
System Design questions ask, “Can you blueprint a scalable, bulletproof system?” You’ll be judged on system architecture smarts, database design flair, scalability instincts, performance tweaks, and the art of trade-offs.
In these questions, you might build distributed systems, tinker with microservices setups, or craft high-availability solutions. Here’s a taste of what might come your way:
| Question | Description |
|---|---|
| Design a URL Shortening Service | Design how to shrink long URLs efficiently and make sure folks get routed back to the original page seamlessly. |
| Design a Collaborative Code Editing Platform | Envision a platform where coders can tag-team in real-time, equipped with all the fancy trimmings like syntax highlighting and version control. |
