Essential Work Sample Exercises for Evaluating Specialized AI Agent Development Skills

Developing specialized AI agents for specific domains requires a unique blend of technical expertise, domain knowledge, and creative problem-solving abilities. Unlike general-purpose AI systems, domain-specific agents must be finely tuned to understand the nuances, terminology, and workflows of particular industries or use cases. This specialization demands that developers not only master AI fundamentals but also develop the ability to translate domain requirements into effective agent behaviors.

The challenge for hiring managers lies in accurately assessing candidates' capabilities in this multifaceted skill area. Traditional interviews often fail to reveal a candidate's true ability to bridge the gap between technical implementation and domain adaptation. Without practical demonstrations, it's difficult to evaluate how well a candidate can design AI agents that truly understand and operate effectively within specialized contexts.

Work samples provide a window into how candidates approach the complex task of specialized agent development. They reveal critical thinking patterns, technical implementation skills, and the ability to empathize with domain users—all essential qualities for success in this field. By observing candidates tackle realistic challenges, hiring managers can make more informed decisions about who will excel at creating AI agents that deliver genuine value in specific domains.

The following exercises are designed to evaluate candidates across the full spectrum of specialized AI agent development skills.

Frequently Asked Questions

How technical should these exercises be? Some candidates may be stronger in domain knowledge than coding.

These exercises are designed to evaluate a blend of skills. While Activity #3 requires hands-on coding, Activities #1, #2, and #4 can be completed with varying levels of technical detail. Adjust the technical depth based on the specific role requirements, allowing candidates to demonstrate their strengths in either technical implementation or domain adaptation.

How can we ensure these exercises are fair when candidates might have varying familiarity with different domains?

Choose domains that align with your company's focus but provide sufficient background information for all candidates. The exercises evaluate how candidates approach domain adaptation rather than testing pre-existing domain knowledge. Consider allowing candidates to choose between 2-3 domain options to showcase their strengths.

How should we weigh performance across these different activities?

Consider the specific requirements of your role. For more technical positions, place greater emphasis on Activities #3 and #4. For roles requiring more stakeholder interaction and requirements gathering, prioritize Activities #1 and #2. The candidate's ability to incorporate feedback is important across all activities and should be a significant factor in evaluation.

Can these exercises be conducted remotely or asynchronously?

Activities #1, #3, and #4 can be adapted for remote synchronous interviews using collaborative tools. Activity #2 requires real-time interaction but can be conducted via video conference. For asynchronous assessment, consider modifying Activity #2 to use a recorded video of a SME interview, though this reduces the interactive element of the exercise.

How much time should we allocate for these exercises in our interview process?

Each exercise requires 45-90 minutes to complete properly. Rather than attempting all four in a single interview day, select 1-2 exercises most relevant to your specific needs. Alternatively, you could use a simplified version of one exercise as an initial screening tool, followed by more in-depth exercises for final candidates.

Should we provide these exercises to candidates in advance?

For Activities #1 and #2, providing the domain context in advance allows candidates to familiarize themselves with the terminology and concepts, focusing the exercise on their adaptation skills rather than rapid domain learning. For Activities #3 and #4, providing general information about the type of exercise while keeping specific details for the interview session offers a good balance.
