FDE Interview Prep & 6-Week Plan

Structured preparation beats unstructured anxiety.

Hiring signal: The FDE interview process has a ~15% pass rate across top AI companies. Candidates who execute a structured 6-week preparation plan targeting decomposition case studies, client simulations, system design for integration, and behavioral interviews pass. Candidates who wing it fail. Company-specific prep (OpenAI eval-heavy, Anthropic safety/alignment, Palantir government/decomposition, startups breadth/speed) is the differentiator for final-round success.

What you will learn

Execute Week 1-2: Decomposition case study practice — 10 mock problems, timed 30-min sessions
Execute Week 3: System design for integration — VPC topology, SSO architecture, data pipelines, deployment patterns
Execute Week 4: Client simulation practice — role-play scenarios, communication under pressure
Execute Week 5: Technical deep dive — present and defend a complex AI system, RAG architecture, eval methodology
Execute Week 6: Behavioral and ownership — STAR stories, radical ownership examples, company-specific research

The Problem

The FDE interview process has a ~15% pass rate across top AI companies. The process includes: a decomposition case study (30 min), system design (45 min), client simulation (45 min), technical deep dive (45 min), and behavioral round (30 min). This lesson gives you a structured 6-week preparation plan targeting each round.
