DDI reduces behavioral simulation scoring from 48 hours to 10 seconds with Databricks
DDI's behavioral simulation assessments relied on trained human assessors taking 24 to 48 hours to evaluate and score candidate responses, limiting scalability and driving operational costs. Infrastructure challenges — hardware orchestration, scaling, data privacy, and multi-vendor coordination — had also blocked effective ML automation.
How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · Candidate submits assessment
Candidates complete a behavioral simulation assessment and submit their responses.

Outcome
ML models on Databricks reduced simulation report delivery time from 48 hours to 10 seconds. Prompt optimization with DSPy improved recall from 0.43 to 0.98, and the instruction fine-tuned Llama3-8b reached an F1 score of 0.86 versus a baseline of 0.76. The LLMs demonstrated high reliability and precision in scoring.
