Engineering at Freddie Mac — Java, AWS, and Loan Product Advisor

Freddie Mac's technology operation is centered on Loan Product Advisor (LPA) — the automated underwriting system that's the single most important software product the company runs. The 2025 push under FHFA Director Pulte to "use technology more aggressively" has put engineering investment at the center of the IPO-prep narrative. This module covers the tech stack candidates can expect (Java/Spring Boot, Python, AWS, microservices), the systems they should know by name (LPA, LPA Choice, DPA One, Income Calculator), and how technical interviews are structured. Engineering interviews at Freddie Mac lean less on LeetCode pyrotechnics and more on system design and behavioral fit.
