Anthropic Forward Deployed Engineers sit in the space where product, customer reality, and model behavior meet. Your prep goes better when you treat the interview like an evaluation of how you make deployment decisions under messy constraints, not a trivia test about models.
Consider this situation. A large support organization wants to roll out Claude to help agents answer customer tickets, but they have strict data rules, an existing identity system, and a backlog of internal tools that hold the real answers. Your job, in an FDE-shaped way, is to turn that into a safe, working deployment plan with clear trade-offs.
Anthropic’s product surface area is the set of things customers actually touch when they build with Claude. In practice, that means Claude as a model, the Claude API as the way an app talks to the model, and the enterprise controls that make a security team willing to approve it.
In the support-ticket example, the customer is not asking for “a chatbot.” They are asking for an AI system that can read ticket context, pull the right policy snippets, call internal tools when needed, and keep sensitive data from leaking into places it should not go.
A lot of FDE work here is translating from business goals into concrete build tasks. You end up deciding what data Claude can see, what actions it can take, and how you prove it is behaving acceptably before a wide launch.

Enterprise Reality Wins
In an interview answer, the fastest way to sound junior is to skip identity, data access, and rollout controls and jump straight to prompting.
Anthropic’s interview process changes over time, but candidates commonly report a set of round types that map to core FDE work. The goal is not to memorize a “correct” sequence. The goal is to understand what each round is trying to predict about how you would perform on an engagement like the support-ticket rollout.
A recruiter screen usually tests whether you can explain your past customer-facing technical work clearly and whether your motivation fits the role. A case-style round often tests discovery, which is the skill of turning an unclear request into a crisp problem statement, constraints, and next steps without making the customer do the engineering for you.
A system design round often focuses on Retrieval-augmented generation (RAG), which is using a search step over customer data to ground the model’s answer before it speaks. In our example, that might mean retrieving the current refund policy and region-specific exceptions so the agent gets an answer that matches today’s rules, not a plausible sounding guess.
An implementation or debugging round tends to test whether you can actually ship. That includes reading logs, isolating failure modes like tool timeouts or bad retrieval, and making targeted fixes without rewriting the whole system.
A behavioral or writing round often tests whether you can communicate trade-offs, risks, and status in a way that builds trust with both engineers and non-engineers. In the rollout, that could be a short brief explaining why you are gating tool use behind allowlists and why you are starting with one queue before expanding.
