Frequently Asked Questions

How long should we allocate for these work samples in our interview process?

Each of these activities is designed to take 45-60 minutes, including time for setup, execution, feedback, and candidate revision. If you're incorporating multiple activities, consider spreading them across different interview stages or dedicating a half-day assessment center approach for final candidates.

Do we need data science expertise on our interview panel to evaluate these exercises?

While having someone with data science knowledge is helpful, especially for Activities #1 and #4, the exercises are designed to evaluate both technical understanding and business application. Sales or marketing leaders can assess the business relevance of the candidate's approaches, even without deep technical expertise.

How can we adapt these exercises for candidates with different levels of experience?

For more junior candidates, provide additional structure and guidance in the prompts. For senior candidates, add complexity such as multiple business units with different needs or international markets with varying data privacy regulations. The core activities remain the same, but you can adjust the scope and constraints.

What if our company doesn't currently use AI-powered lead scoring?

These exercises are still valuable even if you're just beginning your AI journey. Focus more on Activities #2 and #3, which assess a candidate's ability to design new systems and communicate their value. The candidate's approaches will give you insights into how they would help build these capabilities from scratch.

Should we share these exercises with candidates in advance?

For Activities #1, #2, and #4, providing the basic scenario 24-48 hours in advance can result in more thoughtful responses. However, the specific data and details should only be shared during the interview. For Activity #3 (the role play), giving candidates the basic context but not the specific objections creates a more realistic assessment of their communication skills.

How do we evaluate candidates who propose approaches different from what we currently use or plan to implement?

Focus on the reasoning behind their choices rather than alignment with your current approach. Strong candidates should be able to explain why their recommended approach is appropriate for the given scenario, even if it differs from your existing systems. This diversity of thought might actually bring valuable new perspectives to your team.

AI-powered lead scoring and prioritization is rapidly becoming a must-have capability for high-performing sales and marketing organizations. By incorporating these work samples into your interview process, you'll be able to identify candidates who can truly drive value through these systems, rather than those who simply have theoretical knowledge.
