Senior Software Engineer - Frontend | Okta | Bangalore
Apple onsite
Summary
I recently completed an onsite interview at Apple, which included two specific LeetCode problems and discussions on computer science fundamentals. Although I ultimately received an offer from Google, my experience at Apple was valuable.
Full Experience
During my onsite interview at Apple, I was presented with two coding challenges: Course Schedule (LeetCode 207) and Pacific Atlantic Water Flow (LeetCode 417). Beyond the coding, a significant portion of the interview involved in-depth discussions on core computer science fundamentals and various debugging methodologies. While I ultimately accepted an offer from Google, I gained valuable insights into Apple's technical interviewing process through this experience.
Interview Questions (2)
There are a total of numCourses courses you have to take, labeled from 0 to numCourses - 1. You are given an array prerequisites where prerequisites[i] = [ai, bi] indicates that you must take course bi first if you want to take course ai. For example, the pair [0, 1] indicates that you have to take course 1 before course 0. Return true if you can finish all courses. Otherwise, return false.
Given an m x n integer matrix heights representing the height of each unit cell in a continent, your task is to find a list of grid coordinates (row, col) where water can flow to both the Pacific and Atlantic oceans. Water can flow from a cell to an adjacent cell if the adjacent cell has a height less than or equal to the current cell's height. Both the Pacific and Atlantic oceans touch the border of the continent.
