This internship sounds heavily focused on the physical infrastructure side of data centres — essentially the systems that keep servers powered, cooled, and operational 24/7. It aligns strongly with electrical, mechanical, and energy systems engineering. Here’s what each part likely means: Critical power systems High-reliability electrical systems that ensure data centres never lose power. Includes: UPS systems PDUs Backup generators Switchgear Transformers Protection coordination Power distribution and redundancy (N+1, 2N architectures)

I prepped for weeks — LeetCode hard problems, system design diagrams, behavioral stories mapped to every Leadership Principle. The loop was five rounds, back-to-back. They asked me to design a URL shortener, then 'Tell me about a time you failed.' I gave it everything. Now I wait. The bar raiser decides.
