AI Developer Interview Questions to Ask
01
When would you use RAG instead of fine-tuning?
Look for: RAG for changing factual knowledge and citations; fine-tuning for format, tone or task behavior.
02
How do you measure whether an LLM feature is good enough to ship?
Look for: evaluation datasets, faithfulness and accuracy metrics, regression testing.
03
How do you reduce hallucinations?
Look for: grounding, citations, confidence thresholds, "I don't know" fallbacks.
04
How would you cut LLM costs by half?
Look for: smaller models for easy tasks, routing, caching, prompt compression, batching.
05
How do you defend against prompt injection?
Look for: treating retrieved content as data, tool permission limits, input and output filters.
06
How do you handle PII and data residency?
Look for: redaction, zero-retention APIs, private endpoints, access control.

Is my data safe with a remote AI developer?
<p>Yes. Developers sign NDAs, work under your access controls, use zero-retention model APIs or private endpoints, and redact personal data before it reaches any model.</p>
Who owns the AI models, prompts and code?
<p>You do. All code, prompts, evaluation datasets, fine-tuned model weights and intellectual property created for your project belong to you.</p>
Should I hire an AI developer or an AI development company?
<p>Hire a dedicated AI developer when you have a product team and want extra AI capacity under your direction. Choose an AI development company for an end-to-end project with fixed scope and delivery ownership. PerfectionGeeks offers both.</p>
Can I hire an AI developer for a short project?
<p>Yes. Hourly engagements suit prototypes, audits and fixes for underperforming AI features, and you can switch to full-time later.</p>
