About the Salesforce Machine Learning Engineer hiring loop

Salesforce interviews lean enterprise-software: Apex, Lightning Web Components, multi-tenant architecture, governor limits. The "V2MOM" framework anchors leadership rounds. Customer-success orientation is scored explicitly.

ML Engineering rounds score on ML system design depth (latency, throughput, freshness, fairness trade-offs), training-infra fluency, and the bridge between model offline metrics and product KPIs. Coding is secondary to ML system thinking.
