How to structure the interview to assess skills and cultural fit for {role_name}

Work sample test (Home assignment)

Assess the candidate’s practical skills by assigning a real-world task similar to the work they would do if hired.

Title: Design and Optimization of a Mechanical Component
Objective:
To assess the candidate’s ability to design a mechanical part, apply CAD software, and optimize the design for manufacturability and performance.
Requirements:
- Design a basic mechanical component (e.g., a bracket) using AutoCAD or SolidWorks.
- Perform a stress analysis to ensure it can withstand a specified load.
- Optimize the design to minimize material usage while maintaining structural integrity.
- Submit the CAD file, stress analysis report, and a brief explanation of design decisions.
Time Frame: 5 days

Questions based on home assignment :

Once done with work sample test evaluate the candidate’s technical proficiency based on the work sample task.

Technical questions

Duration : 10 minutes/question

Question: How did you determine the appropriate material for the component design?
- Expected Answer: The candidate should explain how they selected the material based on mechanical properties such as strength, durability, and cost.
- Sample Answer: "I chose aluminum for its high strength-to-weight ratio and cost-effectiveness. It also has good resistance to corrosion, which is important for this application."
Question: How did you approach the stress analysis, and what software did you use?
- Expected Answer: Look for a clear description of the candidate’s use of Finite Element Analysis (FEA) or other tools to simulate real-world conditions.
- Sample Answer: "I used SolidWorks' built-in FEA tool to simulate the load conditions. The stress analysis showed that the component could handle the expected load with a safety factor of 1.5."
Question: What changes did you make to optimize the design, and how did they affect performance?
- Expected Answer: The candidate should describe how they minimized material usage or adjusted the geometry without compromising the component’s integrity.
- Sample Answer: "I adjusted the bracket’s geometry by reducing unnecessary thickness in low-stress areas, which reduced material usage by 15% while maintaining its structural performance."

Behavioral questions

Duration : 10 minutes/question

Question: Tell me about a time when you had to redesign a mechanical component due to unforeseen issues during production. How did you handle it?
- Expected Answer: The candidate should describe how they handled the redesign process, including collaboration with manufacturing teams and problem-solving strategies.
- Sample Answer: "During production, we found that the part was too difficult to machine. I collaborated with the manufacturing team to simplify the design, reducing the number of complex features while maintaining functionality."
Question: How do you balance the need for innovation with cost and time constraints in mechanical design projects?
- Expected Answer: The candidate should demonstrate an understanding of how to innovate within project limitations and manage trade-offs between performance and cost.
- Sample Answer: "I prioritize key design features that offer the most value in terms of performance, while reducing costs on non-critical aspects. For instance, I chose a simpler, off-the-shelf component for non-load-bearing parts."
Question: Describe a time when you had to collaborate with a cross-functional team (e.g., design, manufacturing, quality) to complete a project. How did you manage any conflicts or differences in opinion?
- Expected Answer: Look for an example of strong communication, teamwork, and conflict resolution skills.
- Sample Answer: "During a recent project, the manufacturing team raised concerns about the complexity of my design. We had several meetings to discuss their concerns, and I made modifications to ensure manufacturability while maintaining the key design features."

How to evaluate and compare candidates after interviews?

After interviews, it's important to evaluate and compare candidates based on a set of predefined criteria.Use scorecard to evaluate each candidate.

Sample scorecard based on pre-defined criteria. Here’s an example:

Criteria	Sample Question	Rating (1-5)	Comments
CAD Proficiency	How proficient are you with CAD software like AutoCAD or SolidWorks?
Problem-Solving	How did you approach optimizing the mechanical design?
Stress Analysis/FEA Knowledge	How did you perform the stress analysis, and what factors did you consider?
Manufacturability	How did you ensure that the component was optimized for manufacturing?
Teamwork and Collaboration	Describe a situation where you collaborated with other teams to solve a design challenge.
Cultural Fit	How well does the candidate align with our team culture and values?
Communication Skills	Did the candidate effectively communicate technical concepts and collaborate with the team?

What criteria should be used to make the final hiring decision?

Final decisions should be based on the candidate's overall evaluation score, with a focus on important qualifications. Prioritize technical skills above everything else for a {role_name}, but do not forget about communication and cultural fit.
