Interview Question Bank

Backend Engineer • Coding • medium

Design a data structure that implements an LRU (Least Recently Used) Cache. It should support get and put operations in O(1) time complexity. How would you adapt this for caching user session data in Adobe Experience Manager?

Given an array of intervals where intervals[i] = [starti, endi], merge all overlapping intervals. This is often used in Adobe Premiere Pro's backend to calculate total rendered video time on a timeline.

#Arrays #Sorting

Backend Engineer • Coding • medium

Given a string s and a dictionary of strings wordDict, return true if s can be segmented into a space-separated sequence of one or more dictionary words. Consider this in the context of Adobe Acrobat's OCR text extraction.

Write a function to serialize and deserialize a binary tree. This is similar to how we might serialize a complex DOM tree in Adobe XD for network transmission.

Given a 2D grid map of '1's (land) and '0's (water), count the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically.

#Graphs #DFS #BFS

Given an array of non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it can trap after raining.

Design an in-memory file system. Implement commands like ls, mkdir, addContentToFile, and readContentFromFile. This mimics the backend structure of Adobe Cloud storage.

#Trie #Hash Map #Object Oriented Design
Practice
Backend Engineer • Coding • easy

Given a stream of integers, design a class to find the kth largest element in the stream.

#Heap #Priority Queue #Data Streams

Backend Engineer • Coding • hard

Given two strings s and t, return the minimum window in s which will contain all the characters in t. If there is no such window, return an empty string.

#Sliding Window #Hash Map #Strings

Backend Engineer • Coding • easy

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution.

#Arrays #Hash Map

Backend Engineer • Coding • hard

Given a binary tree, find the maximum path sum. The path may start and end at any node in the tree.

#Trees #DFS #Dynamic Programming

Backend Engineer • Coding • medium

Design a data structure that follows the constraints of a Least Recently Used (LRU) cache. How would you implement this to be thread-safe for a high-throughput backend service?

#Hash Table #Doubly Linked List #Concurrency
Practice
Backend Engineer • Coding • medium

Given an array of intervals representing page ranges to extract from a PDF in Adobe Document Cloud, merge all overlapping intervals and return an array of the non-overlapping intervals.

#Arrays #Sorting
Practice
Backend Engineer • Coding • medium

Given an integer array of event IDs from Adobe Analytics and an integer k, return the k most frequent elements. You must solve it in better than O(n log n) time complexity.

#Heap #Hash Table #Bucket Sort
Practice
Backend Engineer • Coding • medium

Given a string representing a user's search query on Adobe Stock and a dictionary of valid tags, return true if the string can be segmented into a space-separated sequence of dictionary words.

#Dynamic Programming #Trie #Memoization
Practice
Backend Engineer • Coding • medium

There are a total of numAssets you have to load for an Adobe Premiere Pro project, labeled from 0 to numAssets - 1. You are given an array prerequisites where prerequisites[i] = [a, b] indicates that you must load asset b first if you want to load asset a. Return true if you can finish loading all assets.

Given an elevation map where the width of each bar is 1, compute how much water it can trap after raining. This is used in our image processing algorithms for histogram analysis.

Design a multithreaded web crawler to scrape asset metadata from external partner sites. How do you ensure you don't process the same URL twice and respect domain rate limits?

#Concurrency #Graph Traversal #Thread Pool

Given a sorted dictionary of an alien language, find the order of characters in the language. Return a string of the unique letters sorted in lexicographical order by the rules of this new language.

#Graph #Topological Sort #String

Given two strings s and t, return the minimum window in s which will contain all the characters in t. If there is no such window, return the empty string.
