Austrian E-Commerce Firm Cuts Candidate Screening Cycle Time 40% with AI Pilot

Background: A Mid-Sized Austrian E-Commerce Operator

This case study is a composite based on patterns observed across Forfis engagements. It does not describe a single named client. The details are drawn from multiple projects in the e-commerce and retail sector, with identifying information removed. The company, the metrics, and the timeline are representative of what Forfis has delivered for similar clients in Tier-1 European markets.

The client is a mid-sized e-commerce operator in Austria, with 120 employees and a growing online retail operation. The company sells consumer goods through its own website and third-party marketplaces. It operates in German, English, and increasingly in other European languages. The HR team is small: two recruiters and one HR generalist. The company uses a standard ATS (applicant tracking system) and a CRM for candidate management. The stack includes a custom REST API for internal integrations and webhooks for event-driven updates.

Challenge: Scaling HR Without New Hires

The company was scaling its online retail operation and needed to hire more customer service and logistics staff. The HR team was overwhelmed: they were receiving 200-300 applications per month, mostly in German and English, with a growing share in other European languages. The recruiters were spending 4-6 hours per day on initial screening: reading resumes, extracting key information, and drafting first responses. The cycle time from application to first response was 5-7 days. The error rate on manual data entry was 8-12%, leading to follow-up calls and candidate frustration.

The operational pressure was clear: the company could not hire more recruiters without increasing headcount, which was not in the budget. They needed to scale operations without new hires. The compliance context was also important: the company handles payment card data in its e-commerce operations, so PCI DSS compliance was a baseline requirement. Any AI system touching candidate data had to respect GDPR and data residency rules.

Approach: Fixed-Scope Pilot with LangChain and LangGraph

Forfis started with a process audit. The team mapped the candidate screening workflow: application intake, resume parsing, skill extraction, first-response drafting, and recruiter review. The audit identified two high-value automation targets: document and data extraction from resumes, and conversational first-response triage. The client chose candidate screening as the pilot scope.

The architecture used LangChain and LangGraph. LangChain handled the LLM calls for extraction and conversation. LangGraph managed the state machine: parsing, validation, escalation, and response drafting. The extraction pipeline parsed PDFs and DOCX files, extracted structured fields (name, email, phone, skills, experience), and validated them against a schema. The conversational agent handled first-response triage: it greeted the candidate, asked clarifying questions, and drafted a screening summary. A human recruiter reviewed the draft before it went out.

The integration used a custom REST API and webhooks. The ATS called the Forfis API to trigger the agent, and the agent called the ATS API to write back the screening result. The system was model-agnostic: OpenAI and Anthropic APIs for quality-critical tasks, open-weight models on the client’s hardware for data that could not leave the building.

Outcome: Cycle Time and Error Rate Improvements

The pilot ran for 6 months. The first 2 months were setup: API integration, prompt engineering, and baseline measurement. The next 4 months were live operation with human review. The final 2 months were analysis and iteration.

The results were measured against the baseline. Cycle time from application to first response dropped from 5-7 days to 1-2 days. The error rate on data entry dropped from 8-12% to 2-3%. The recruiters reported that they spent 60-70% less time on initial screening and could focus on higher-value tasks like interviewing and candidate relationship management. The multilingual coverage improved: the agent handled German, English, and French applications with consistent quality, reducing the need for manual translation.

The pilot met the success criteria defined in the scope document. The client decided to roll out the system to additional departments and role families. The rollout plan included a second pilot for customer service ticket triage, using the same LangGraph architecture but with a different state machine and tool set.

Lessons for Similar Teams

• Start with a process audit, not a technology choice. The audit identified the workflows worth automating. Without it, the team would have spent time on low-value tasks or missed high-value ones. The audit also established the baseline metrics that made the pilot measurable.

• Fixed-scope pilots prevent drift. The scope document specified one workflow, one department, and one success metric. Any change triggered a change order. This kept the 6-month timeline realistic and prevented the pilot from becoming a full platform build.

• Human-in-the-loop is non-negotiable for regulated data. The agent drafted, the human approved. This was critical for GDPR compliance and for building trust with the recruiters. The human review step also caught edge cases that the model missed, which fed back into prompt engineering.

• Model-agnostic architecture reduces lock-in. The system used OpenAI and Anthropic APIs where quality mattered, and open-weight models on the client’s hardware where data residency was required. This allowed the client to swap models as they became available or as costs changed, without re-architecting the system.

• Integration through existing APIs, not replacement. The system plugged into the client’s ATS and CRM through their APIs. This reduced implementation risk and kept the client’s existing workflows intact. The client did not have to migrate data or change their tools.
