LLM Engineering & Agent Orchestration
LLM engineering is central to Agentforce and Einstein capabilities. You’ll be assessed on prompt design, tool/function calling, RAG, evaluation, and observability—plus how you harden agents for correctness, latency, and cost. Expect to discuss trade-offs between hosted APIs and open-source models, as well as alignment and safety mitigations.
- Be ready to go over:
- Prompt and system design: instruction hierarchies, templating, few-shot strategies, guardrails
- Tool use & orchestration: function calling, multi-step plans, planner-executor patterns
- Retrieval (RAG): chunking, embeddings, vector stores, freshness/versioning
- Advanced concepts (less common): structured outputs (JSON schemas), constrained decoding, function routers, multi-agent patterns, evaluation harnesses (hallucination, robustness), cost/latency modeling
- Example questions or scenarios:
- "Design an agent to triage and resolve service cases using knowledge articles and CRM data—ensure safe actions and low latency."
- "Walk through your approach to evaluate hallucination risk and implement automated regression tests for prompts."
- "Given spike in token costs, how would you refactor orchestration to reduce spend without quality loss?"
Data Engineering on Salesforce & External Stacks
Reliable AI begins with production-grade data. You’ll be evaluated on your ability to model, ingest, transform, and govern data across Salesforce Data Cloud and external platforms (e.g., Snowflake, Databricks). The focus is on pipelines that are observable, lineage-aware, and built for AI workloads.
- Be ready to go over:
- Data modeling: harmonizing CRM entities, unifying profiles, schema evolution
- Pipelines: batch vs. streaming, CDC, orchestration, backfills, SLAs
- Governance & security: PII handling, RBAC, data residency, auditability
- Advanced concepts (less common): feature stores, vectorization pipelines, semantic caching, retrieval freshness SLAs
- Example questions or scenarios:
- "Design a pipeline to keep knowledge articles and case data fresh for RAG within a 5-minute SLA."
- "How would you track lineage and rollback when a bad transformation pollutes embeddings?"
- "Describe how you’d partition and cache data to meet a 500ms retrieval target."
Platform Engineering & Salesforce Integration (Apex, Flows, LWC)
Many roles require integrating AI into the Salesforce Platform experience. Interviewers probe your ability to embed agents into workflows, use Apex/Flows, and surface capabilities via Lightning Web Components with robust error handling and telemetry.
- Be ready to go over:
- Apex services and governor limits: bulkification, async patterns, callouts
- Flows and orchestration: invoking AI steps safely, human-in-the-loop approvals
- LWC UX: responsive components, streaming updates, state management
- Advanced concepts (less common): platform events, Omni-Channel, shield encryption, cross-org packaging
- Example questions or scenarios:
- "Embed an AI suggestion panel in a Service Console LWC with feedback capture and rollback."
- "Design an Apex service that calls an LLM safely within governor limits and retries."
- "How would you add human review checkpoints for high-risk actions triggered by an agent?"
System Design for AI Features at Scale
You’ll be asked to architect systems that meet enterprise SLAs. The bar includes availability, observability, performance, cost control, and safe failure modes. Demonstrate the ability to reason about latency budgets from UI to model response, and the mechanisms to degrade gracefully.
- Be ready to go over:
- Service boundaries & APIs: idempotence, versioning, schema contracts
- Caching strategies: prompt/result caching, semantic caching, TTL policies
- Observability: traces, structured logs, prompt/version tracking, replay
- Advanced concepts (less common): circuit breakers for model timeouts, multi-model routing, canary and shadow deployments
- Example questions or scenarios:
- "Design a multi-tenant AI service with per-tenant quotas and feature flags."
- "Your p95 latency regressed after a model upgrade—diagnose and fix."
- "Plan a rollout with canaries and automated offline/online evals."
Responsible AI, Safety & Evaluation
Trust is non-negotiable. You’ll need to show how you detect and mitigate abuse, jailbreaks, toxicity, bias, and data leakage, and how you evaluate quality rigorously. Expect layered defenses (policy filters, red-teaming, eval suites) and articulate how you keep humans in the loop for sensitive actions.
- Be ready to go over:
- Safety controls: input/output filters, policy engines, rate-limiting, escalation
- Eval methodology: golden sets, adverse prompts, drift monitors, A/B tests
- Compliance: PII handling, audit logs, consent, regional regulations
- Advanced concepts (less common): structured tool-use constraints, alignment strategies, prompt/parameter isolation by tenant
- Example questions or scenarios:
- "Design a safety layer for an agent that can create refunds; include auditability and approvals."
- "How would you construct an eval suite to detect and prevent prompt injection?"
- "Discuss bias mitigation strategies for a lead-scoring use case."
Delivery Excellence & Customer Collaboration (Forward Deployed)
Forward Deployed Engineers are judged on their ability to land value quickly, unblock technical issues, and translate ambiguous requirements into delivered outcomes. You’ll be asked about stakeholder management, rapid prototyping, and operating in mixed environments (customer stacks + Salesforce Platform).
- Be ready to go over:
- Discovery & scoping: clarifying outcomes, constraints, risks, and success metrics
- Rapid iteration: POCs to MVPs, kill/scale decisions, demo discipline
- Runbooks & handoff: documentation, SLAs, support models, training
- Advanced concepts (less common): multi-org rollouts, regulated environments, change management
- Example questions or scenarios:
- "Walk through a 6-week plan to deliver an MVP agent with measurable ROI."
- "A data integration blocker threatens the go-live—how do you unblock and communicate?"
- "How do you align exec sponsors and end-users around adoption and safety?"
