Entry level · FDE track · with diagrams
Ten FDE interview questions with model answers: the role, discovery calls, framing, pilots, integration, AI decisions, RAG, agents and handover. Free, with diagrams, no account.
A forward deployed engineer (FDE) is a software engineer who works inside the customer's world: discovering the real problem on site, building the solution against production data, shipping it into the customer's environment and handing it over with runbooks. Discovery, building, shipping and handover are the four verbs; consulting-flavored engineering with production ownership.
Structure it as people, pain, proof. Who feels the problem and how often; what it costs in time, money or risk; what evidence you saw with your own eyes. End with a one-sentence problem framing and check it with the customer before any solution talk. Interviewers score whether you ask before you propose.
You recover the decision behind the request: which decision should change, who makes it, and what they look at today. A dashboard nobody decides with is shelfware. Strong answers name the decision-maker and the current workaround, then propose the smallest view that changes the decision.
Who suffers, what it costs, where the friction lives. Example: support agents take 11 minutes per ticket because order history lives in three systems. Vague complaints (tooling is bad) and pre-baked solutions (we need AI) are not problem statements; measurable friction is.
Judge by reversibility and blast radius, not purity: is the failure mode understood, is it reversible, and does it have an owner? A reversible, owned workaround can be the right pilot call; an irreversible one never is. Say both the choice and the rollback plan.
Acceptable workaround
Proper fix required
Integration conflicts are ownership conflicts first: name which system owns the record and how the others learn about changes. One owner plus a defined propagation path beats syncing machinery. Say the owner, the propagation and the conflict rule for simultaneous edits.
When a fixed rule covers the cases and every mistake needs an explanation. Models earn their keep on fuzzy patterns at scale; deterministic rules win wherever correctness must be explained case by case. Name the explanation requirement explicitly.
The AI looks up your own documents before answering, and shows which passages it used. Answers stay fresh because nothing is memorized, and every claim can be opened and checked. Retrieval plus generation: fresh passages in, grounded answer out.
Confirmation, preview or undo for every irreversible step. Read steps are cheap; write steps need a gate. The model choice is secondary; action design is the safety story. Name one gate per write action in your answer.
How to know it is broken, who gets paged, and how to roll back, in that order. The handover serves the 3 a.m. reader: detection, escalation, rollback. History and screenshots rank below all three.
Straight answers
Ten questions with model answers and diagrams. Read one, answer aloud, then compare with the model. There is no timer, no account and nothing recorded.
No. They are practice items written for learning and never appear in any job interview bank or certification exam. Scores and answers stay with you; nothing counts toward any assessment.
Study the matching free course for the questions you missed, then test yourself on the sibling practice exam. When both feel easy, look at the certification sittings on the pricing page.
