Top 100 FDE Real Interview Questions and Answer from Big Tech

What Palantir, OpenAI, Anthropic, Scale AI, Databricks, Snowflake, Google and eight more companies ask forward deployed, solutions and customer engineers, sorted by round and tagged by how strong the evidence is.

Forward deployed engineering has gone from a Palantir oddity to a standard title at the AI labs and the data platforms. The interviews are different from a normal software loop. You still write code, but most offers are decided somewhere else: in a round where a vague customer problem lands on the table and you have 45 minutes to turn it into a plan.

We researched the loops at 15 companies and collected 100 questions candidates and prep guides report for these roles. This post is the question list. The full guide gives every question a model answer in STAR form, plus a mock discovery call, three worked designs, one prep page per company, and pay and levelling data. Links are at the end.
