The Screening Bottleneck in Small B2B SaaS Teams
For an 11-50 person B2B SaaS company in Austria, the bottleneck is not a lack of candidates but the time senior staff spend on routine screening. A typical hiring cycle involves parsing 50-100 applications per week, extracting structured data, and drafting first-response emails. This manual work consumes 10-15 hours per week per recruiter, diverting attention from stakeholder alignment and final interviews. The goal is not to replace recruiters but to free them from back-office tasks, enabling them to focus on high-value activities. A conversational agent can handle initial triage, data extraction, and first-response emails, reducing cycle time by 40-60% and error rate by 30-50%. The key is to start with a fixed-scope pilot that measures baseline performance before and after automation, ensuring the investment delivers measurable ROI.
Architecture: LangGraph Stateful Workflows and RAG
The agent is built on LangChain and LangGraph, with LangGraph modeling the screening workflow as a stateful graph. This allows for explicit control flow, including human-in-the-loop checkpoints before any action that affects a candidate’s status. The agent uses a retrieval-augmented generation (RAG) approach to access the company’s job descriptions, competency frameworks, and past hiring data. It compares candidate profiles against these criteria, scores them, and flags mismatches. The scoring logic is transparent and auditable, ensuring decisions are based on documented criteria rather than opaque model outputs. For regulated data, the architecture supports open-weight models on the client’s own hardware, ensuring data does not leave the building. This model-agnostic approach allows the company to use OpenAI or Anthropic APIs where quality matters, while maintaining compliance with EU data protection laws.
Integration with Google Workspace and Existing ATS
The agent integrates with Google Workspace to read and write emails, access the calendar for scheduling, and retrieve documents from Drive. For candidate screening, the agent parses application emails, extracts structured data (name, experience, skills), and drafts responses. This reduces manual data entry and ensures all candidate interactions are logged in a central system. The integration uses Google’s APIs, avoiding the need to replace existing tools. The agent also connects to the company’s ATS (e.g., Greenhouse, Lever) to update candidate records and trigger next steps. This plug-and-play approach ensures the agent fits into the existing workflow rather than forcing a system change. The result is a seamless reduction in back-office work, with all candidate interactions tracked and auditable.
Compliance: EU AI Act and GDPR in Austria
Under the EU AI Act, candidate screening systems are classified as high-risk AI. This requires risk management, data governance, human oversight, and transparency. The agent must operate within a defined scope, and data processing must be documented. Human-in-the-loop design is mandatory for decisions affecting employment, and automated rejections require explicit human review. The system logs all agent actions and human decisions for auditability. In Austria, GDPR also applies, requiring explicit consent and purpose limitation for candidate data. The agent’s scoring logic must be transparent, and candidates must be informed about the use of AI in the screening process. This compliance-first approach ensures the agent meets legal requirements while delivering operational efficiency.
Two-Week Pilot: Scope, Baseline, and Rollout
The pilot is scoped to a two-week timeline, assuming the audit is complete and data access is granted. Week 1 focuses on baseline measurement and agent development: the team measures current cycle time and error rate, builds the LangGraph workflow, and sets up the RAG pipeline. Week 2 focuses on integration and human-in-the-loop setup: the agent connects to Google Workspace and the ATS, and the team configures approval steps for high-stakes actions. The pilot ends with a before/after comparison of cycle time and error rate, providing a clear ROI metric. This fixed-scope approach ensures the pilot is deliverable in two weeks and provides a measurable foundation for rollout. The result is a working agent that reduces manual back-office work and frees senior staff for high-value activities.
