Effective Work Sample Exercises for Hiring Top Supply Chain Managers

Supply Chain Managers serve as the backbone of operational efficiency in modern organizations, orchestrating the complex flow of goods, information, and finances across global networks. Their ability to balance cost efficiency with service excellence directly impacts a company's bottom line and competitive positioning. In today's volatile business environment, characterized by disruptions ranging from pandemic-related shortages to geopolitical tensions, finding a Supply Chain Manager with both technical expertise and adaptive leadership skills is more crucial than ever.

Traditional interviews often fail to reveal how candidates will perform in real-world supply chain scenarios. While resumes highlight past achievements and behavioral interviews explore experiences, these methods rarely demonstrate how candidates analyze data, solve complex problems, or collaborate across departments under pressure. This gap between interview performance and job success can lead to costly hiring mistakes.

Work samples and role plays bridge this gap by simulating actual job challenges. By observing candidates tackle realistic supply chain scenarios, hiring managers gain invaluable insights into their analytical capabilities, decision-making processes, and communication styles. These exercises reveal not just what candidates know, but how they apply that knowledge in practice.

The following four exercises are designed to evaluate the essential competencies of successful Supply Chain Managers: strategic thinking, relationship management, project management, adaptability, and leadership. Each activity simulates a different aspect of the role, from data analysis to cross-functional collaboration, providing a comprehensive view of candidates' capabilities and potential fit within your organization.

By incorporating these exercises into your hiring process, you'll not only identify candidates with the right skills and experience but also those who can translate that expertise into tangible results for your organization's supply chain operations.

Activity #1: Supply Chain Performance Analysis

This activity evaluates a candidate's analytical skills and strategic thinking by presenting them with real supply chain metrics. Supply Chain Managers must regularly analyze performance data to identify inefficiencies and opportunities for improvement. This exercise reveals how candidates approach data analysis, draw meaningful insights, and develop actionable recommendations—core competencies for driving supply chain optimization.

Directions for the Company:

• Prepare a dataset containing 3-6 months of supply chain KPIs such as on-time delivery rates, inventory turnover, lead times, transportation costs, and fill rates. Include some anomalies or concerning trends.
• Create a brief company context document explaining your industry, supply chain structure, and current challenges (1-2 pages).
• Provide the candidate with these materials 24-48 hours before the interview.
• During the interview, allow 20 minutes for presentation and 10 minutes for questions.
• Assign 2-3 interviewers who understand supply chain metrics to evaluate the analysis.

Directions for the Candidate:

• Review the provided supply chain data and company context.
• Analyze the metrics to identify key performance issues, inefficiencies, or opportunities for improvement.
• Prepare a 15-20 minute presentation that includes:

1. Summary of key findings from the data
2. Identification of 2-3 critical issues or opportunities
3. Recommendations for addressing these issues with estimated impact
4. Implementation considerations and potential challenges

• Be prepared to answer questions about your analysis and defend your recommendations.

Feedback Mechanism:

• After the presentation, provide specific feedback on one strength (e.g., "Your identification of the correlation between lead time variability and inventory costs was insightful") and one area for improvement (e.g., "Your recommendations could have included more specific implementation steps").
• Ask the candidate to spend 5 minutes refining one of their recommendations based on the feedback, focusing on making it more specific, actionable, or addressing potential implementation challenges.

Activity #2: Supplier Negotiation Role Play

This role play assesses a candidate's relationship management and communication skills in a common supply chain scenario. Effective supplier negotiations are critical for managing costs, ensuring quality, and building strategic partnerships. This exercise reveals how candidates balance competing priorities, handle difficult conversations, and work toward mutually beneficial outcomes.

Directions for the Company:

• Create a scenario involving a negotiation with a key supplier. Include details such as:
• Background on the supplier relationship (length, importance, past issues)
• Current contract terms and performance metrics
• Business needs driving the negotiation (cost reduction, improved service levels, etc.)
• Constraints or non-negotiables
• Assign someone to play the role of the supplier representative with specific instructions on their position and flexibility.
• Provide the scenario to the candidate 24 hours before the interview.
• Allow 20-30 minutes for the role play.

Directions for the Candidate:

• Review the supplier negotiation scenario and prepare your approach.
• Consider both your immediate objectives (e.g., cost reduction) and long-term relationship goals.
• During the role play:

1. Establish rapport and set a collaborative tone
2. Clearly articulate your needs and priorities
3. Listen actively to the supplier's position
4. Work toward a solution that addresses key business needs while maintaining the relationship
5. Close with clear next steps

• Be prepared to justify your negotiation strategy and decisions afterward.

Feedback Mechanism:

• Provide feedback on one strength (e.g., "You effectively used data to support your position") and one area for improvement (e.g., "You could have explored more creative solutions to address their concerns about volume commitments").
• Ask the candidate to spend 5 minutes role-playing a follow-up conversation that incorporates the feedback, focusing on the specific aspect that needed improvement.

Activity #3: Supply Chain Disruption Response

This scenario tests a candidate's adaptability, problem-solving skills, and crisis management abilities. Supply chain disruptions are increasingly common, and managers must respond quickly and effectively to minimize impact. This exercise reveals how candidates prioritize actions, make decisions with incomplete information, and balance short-term needs with long-term resilience.

Directions for the Company:

• Develop a realistic supply chain disruption scenario relevant to your industry (e.g., supplier bankruptcy, natural disaster affecting a key manufacturing location, transportation strike, or sudden regulatory change).
• Create a brief document with:
• Description of the disruption
• Immediate business impact
• Available resources and constraints
• Key stakeholders involved
• Optionally, prepare "update" information to introduce during the exercise to test adaptability.
• Allow 30-45 minutes for the complete exercise.

Directions for the Candidate:

• Review the disruption scenario and consider your immediate response and recovery strategy.
• Prepare a response plan that includes:

1. Immediate actions (first 24-48 hours)
2. Short-term mitigation strategies (1-2 weeks)
3. Long-term recovery and resilience building (1-3 months)
4. Communication approach for different stakeholders (customers, internal teams, suppliers)

• Present your plan (10-15 minutes) and be prepared to answer questions and adapt as new information is provided.
• Focus on demonstrating both decisive action and thoughtful consideration of various impacts and trade-offs.

Feedback Mechanism:

• Provide feedback on one strength (e.g., "Your prioritization of customer communication was excellent") and one area for improvement (e.g., "Your plan didn't fully address the financial implications of the proposed solutions").
• Ask the candidate to spend 5-10 minutes revising one aspect of their plan based on the feedback and any new information provided during the discussion.

Activity #4: Cross-Functional Project Planning

This exercise evaluates a candidate's project management skills, leadership abilities, and cross-functional collaboration. Supply Chain Managers must regularly lead initiatives that span multiple departments and balance competing priorities. This activity reveals how candidates structure complex projects, anticipate challenges, and engage stakeholders effectively.

Directions for the Company:

• Create a scenario for implementing a significant supply chain improvement project, such as:
• Implementing a new inventory management system
• Redesigning the distribution network
• Launching a supplier sustainability program
• Integrating operations after an acquisition
• Prepare a document outlining project objectives, constraints (budget, timeline), and stakeholders from different departments (IT, Finance, Operations, Sales).
• Assign 3-4 interviewers to play the roles of different department representatives with specific concerns and priorities.
• Allow 45-60 minutes for the complete exercise.

Directions for the Candidate:

• Review the project scenario and develop a high-level implementation plan.
• Prepare a 15-minute presentation covering:

1. Project approach and key milestones
2. Resource requirements and budget considerations
3. Risk assessment and mitigation strategies
4. Stakeholder management and communication plan
5. Success metrics and evaluation approach

• Following your presentation, participate in a 20-30 minute meeting with cross-functional stakeholders (played by interviewers).
• Demonstrate your ability to address concerns, build consensus, and adapt your plan based on stakeholder input.

Feedback Mechanism:

• Provide feedback on one strength (e.g., "You effectively addressed the IT department's concerns about system integration") and one area for improvement (e.g., "You could have more explicitly connected the project to business outcomes important to the Finance team").
• Ask the candidate to spend 5-10 minutes revising their stakeholder engagement approach based on the feedback, focusing specifically on how they would better address the concerns of one particular department.

Frequently Asked Questions

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

Each exercise requires approximately 30-60 minutes, including preparation, execution, and feedback. We recommend selecting 1-2 exercises most relevant to your specific needs rather than attempting all four. Consider spreading them across different interview stages or combining complementary activities in a half-day assessment.

Should we provide these exercises to all candidates or only finalists?

These exercises are most valuable for evaluating final-round candidates after you've screened for basic qualifications and experience. They require significant time investment from both candidates and your team, so reserve them for candidates who have already demonstrated potential through initial interviews.

How should we evaluate candidates' performance on these exercises?

Create a structured evaluation rubric for each exercise based on the key competencies it tests. For example, the Supply Chain Performance Analysis should be evaluated on analytical rigor, insight quality, recommendation practicality, and presentation clarity. Have multiple evaluators use the same rubric to reduce individual bias.

What if a candidate has limited experience with our specific industry or supply chain model?

Provide sufficient context in your scenario materials to enable candidates from different backgrounds to participate meaningfully. Focus your evaluation on their approach, reasoning, and transferable skills rather than industry-specific knowledge. The best candidates will ask clarifying questions and adapt their approach to your context.

How can we ensure these exercises don't disadvantage candidates from underrepresented groups?

Review all materials for potential bias in language or assumptions. Provide clear instructions and equal preparation time to all candidates. Consider offering accommodations when appropriate. Focus evaluation on objective criteria directly related to job performance, and use multiple evaluators with diverse perspectives.

Can we modify these exercises for remote interviews?

Yes, all these exercises can be adapted for virtual settings. Use video conferencing platforms with screen sharing for presentations, provide materials through secure file sharing, and use breakout rooms for role plays. Consider extending time slightly to account for technology transitions and potential connectivity issues.

In today's complex and volatile business environment, finding the right Supply Chain Manager can significantly impact your organization's operational efficiency and competitive advantage.
