Forward Deployed Engineer Interview Field Manual

Forward deployed engineering rewards a background that traditional engineering ladders undervalue: breadth, client work, delivery under someone else's constraints, and a tolerance for messy problems. If that describes your career, you are closer to this role than you think.

But two rounds in the FDE loop have no equivalent in a normal engineering interview - the customer role-play and the take-home prototype - and they are where candidates are eliminated.

Inside

• The role and the loop - three archetypes, seven rounds, what each one scores and how each is failed.


• Engagement craft - customer discovery, scoping and the statement of work, the five-day prototype.


• The technical ground - data integration reality, deployment topologies, enterprise LLM work, agents in a customer environment, security review.


• Running it - stakeholders, cadence, scope creep, handover, and the bespoke-to-product loop the role exists for.


• Practice - six role-play scripts with weak and strong responses, three worked case interviews, and a one-page field card for the morning itself.

14 chapters. 3 worked cases. 6 role-play scripts.

For consultants, professional-services engineers, enterprise integrators and solution architects moving into product companies - and anyone whose best work has been the first six weeks, before anyone agrees what the problem is.
