The Sierra Forward Deployed Engineer interview loop, round by round

Conversational agents, and the evals specific to customer service.

One candidate report · August 2026 · 1 rounds mapped · 3 open FDE roles

Thin public data. The loop is reported to centre on agent system design, conversational architecture, and evaluation built for customer-service behaviour.

How we know this. A single reported question plus the loop's general shape. Treat the stage list as incomplete.
