FDE vs SWE interview

The job pages keep drawing a line: not support, not solutions, not pre-sales, not a standard implementation seat. They name judgment as the peer of engineering. We did not find a numbered interview sequence on this freeze. Do not memorize one.

Sourced from opened JDs. Not from a war story. Not from a named-company “our process” page.

They say it is not that other job

“This is not a traditional support or solutions role. Customer FDEs are engineers first.”

Amplitude — Senior Customer Forward Deployed Engineer

“This isn't a traditional pre-sales role or a back-office delivery position. It's a highly autonomous customer-facing engineering role.”

AvePoint — Forward Deployed Engineer - AI

“This is not a standard implementation role. It sits at the intersection of engineering, product judgment, and customer reality.”

Protege — Forward Deployed Engineer, New Verticals

Judgment is not a soft skill bolted on

“Agency, judgment, and customer understanding are equally if not more valuable in this role as strong software engineering ability.”

Poetic — Forward Deployed Engineer

“Navigate ambiguity and exercise good judgment on tradeoffs and tools needed to solve problems.”

Baseten — Forward Deployed Engineer

“You thrive where there's no playbook...you set the goalposts with the customer and build to them.”

Minerva — Forward Deployed Engineer, Data Systems

What a leetcode loop misses

From the opened language, not from a war story. Ambiguity is the default (47 of 88). Scoping is named work (18). Customer-facing is in 46. Executive stakeholders in 24. Travel in 35. Production code in someone else’s house — VPC, on-prem, their SSO — is the job (Reducto: “VPC to bare metal on-prem”).

A generic leetcode-plus-system-design loop tests the left column of the skill map and skips the right. That is the gap.

If the JD says…The loop has to test…
first FDE / writing the playbookCan you invent a motion, and say what you will not promise
ambiguity / scopingCan you decompose a messy ask and hold a boundary
customer-facing / embedded / on-siteCan you work in their environment, not yours
stakeholders / executive stakeholdersCan you talk to a buyer without becoming pre-sales
integrations / production deployments / go-liveCan you still ship, in their stack, to live

Those stage names (recruiter screen → technical → customer scenario → stakeholder → onsite) are a working model. They are not a sourced sequence from OpenAI, Palantir, or anyone else on this freeze. Do not memorize them as “the loop.” Use them as a checklist against a specific JD.
