Received an invitation for the Salesforce Futureforce Coding Challenge via HackerRank. The test had a strict 60-minute time limit and used AI Proctor Mode, which monitored for screen switching, tab changes, or copy-pasting.
Interview questions [2]
Question 1
Question 1: Bit Pattern Generator
Short Description: Given an array of integers, determine for each element whether it has appeared previously in the array and whether it will appear again later. Generate two binary strings representing these historical and future occurrences using an efficient hashing approach to achieve O(n) time complexity.
Question 2: Cloud Pods Optimization
Short Description: Process a stream of specific and global threshold capacity updates on a set of microservice pods. To avoid performance bottlenecks on massive datasets, the solution leverages a Lazy Propagation strategy combined with a Suffix Max array, resolving complex historical updates in optimal O(n + m) time instead of a naive nested loop approach.
