The Salesforce interview process comprised five distinct rounds starting with an Online Assessment on HackerRank focusing on Arrays, Strings, and Graphs. This was followed by a Virtual Screening round and two Onsite technical rounds that heavily tested Data Structures and Algorithms, binary search, heaps, dynamic programming, and low-level data structure design. The process concluded with a comprehensive Hiring Manager round covering behavioral aspects, past project architecture, ownership, and conflict resolution. Overall, the interview was moderately difficult and placed a strong emphasis on clean code, optimization, and system design fundamentals.
