Cracking HRT's Technical Rounds -- C++, Systems Design, and Low-Latency Thinking

HRT's technical interviews test C++ depth, systems thinking, and low-latency engineering knowledge that goes beyond standard LeetCode prep. This module covers the specific technical topics HRT tests -- from cache-line padding and false sharing to market data pipeline design -- with real questions reported by candidates and a structured preparation framework. If you are interviewing for an SWE or Core Developer role, this module is essential.
