Given a string s, find the length of the longest substring without repeating characters.

#Sliding Window #Hash Table #Strings
Software Engineer Coding hard

Serialize and deserialize a binary tree. Design an algorithm to encode a tree to a single string and decode it back to the original tree structure.

#Trees #Depth-First Search #Breadth-First Search #Design
Software Engineer Coding medium

Given an array of intervals where intervals[i] = [start_i, end_i], merge all overlapping intervals, and return an array of the non-overlapping intervals that cover all the intervals in the input.

#Arrays #Sorting
Software Engineer Coding medium

Design a data structure that supports insert, remove, and getRandom operations in O(1) average time complexity.

#Hash Table #Arrays #Design
Software Engineer Coding medium

Given the root of a binary tree, return the zigzag level order traversal of its nodes' values. (i.e., from left to right, then right to left for the next level and alternate between).

#Trees #Breadth-First Search #Queues
Software Engineer Coding hard

Given an m x n board of characters and a list of strings words, return all words on the board. Each word must be constructed from letters of sequentially adjacent cells (horizontal/vertical).

#Trie #Depth-First Search #Backtracking
Software Engineer Coding easy

Given the head of a singly linked list, reverse the list, and return the reversed list.

#Linked Lists #Pointers
Software Engineer System Design hard

Design a distributed file storage and synchronization system like Microsoft OneDrive. How do you handle file chunking, cross-device synchronization, and conflict resolution?

#Distributed Systems #Data Consistency #Block Storage #Concurrency
Software Engineer System Design hard

Design the backend presence service for Microsoft Teams (online, offline, away, busy). It needs to handle millions of concurrent users with extremely low latency.

#WebSockets #High Availability #Redis #Fan-out Architecture
Software Engineer System Design hard

Design a real-time collaborative text editor like Microsoft Word Online. Focus on how you would handle concurrent edits from multiple users and maintain document consistency.

#Operational Transformation (OT) #CRDTs #Concurrency #WebSockets
