Snapchat Interview Real Question Sharing

1. Coding
   Given an integer array nums and an integer k, please find the maximum value in all sub-arrays of size k in the sliding window.
   Input:
   nums = [1,3,-1,-3,5,3,6,7], k = 3
   Output:
   [3,3,5,5,6,7]
   Explanation:
   Use a deque to maintain the maximum value in the sliding window to achieve a time complexity of O(n).
2. System Design Example: Design a Story Feature
   Question Requirements:
   Design a system to support users in uploading, viewing, and expiring “Story” content.
   Functional Requirements:
   • Users can upload video or picture stories within 10 seconds.
   • Stories automatically expire after 24 hours.
   • Users can view all active stories in their friend list.
   • Support high concurrent requests and quick responses.
3. Behavioral
   • Please share a project experience that you were responsible for from start to finish and drove to completion.
   • Have you ever encountered a situation where the data was incomplete or the information was insufficient? How did you make decisions?
   • Please share your experience in a project with a very tight schedule and a fast pace.
   • Please describe an experience where you received negative feedback. How did you respond to it? What did you learn from it?
   • Have you ever had an experience where you needed to explain complex technical concepts to people without a technical background? How did you do it?
