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 Troubleshoot a Power Distribution System
Objective:
Evaluate the candidate’s ability to design a basic power distribution system for a manufacturing plant and troubleshoot potential electrical issues in the system.
Requirements:
- Design a power distribution layout using CAD software for a medium-sized manufacturing plant, including transformers, circuit breakers, and control systems.
- Create a brief document explaining the design and safety considerations.
- Identify and troubleshoot at least three common issues that could arise in the system, providing solutions for each.‍
‍Time Frame:3-4 days to complete the assignment.

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

How did you ensure the safety and reliability of the power distribution system in your design?
- Expected Answer: The candidate should discuss safety features like circuit breakers, grounding, and surge protection. They should also reference relevant safety codes (e.g., NEC).
- Sample Answer: "I included circuit breakers to protect against overcurrent, grounding for safety, and surge protectors to prevent damage from electrical spikes. I also ensured compliance with NEC standards."
What are the main considerations when choosing transformers for a power distribution system?
- Expected Answer: Factors such as load capacity, voltage levels, efficiency, and cooling systems should be discussed.
- Sample Answer: "I selected transformers based on the load capacity required by the plant, ensuring that the voltage levels match the system requirements. I also chose transformers with efficient cooling systems to prevent overheating."
How did you troubleshoot the issues you identified in your system, and what solutions did you propose?
- Expected Answer: The candidate should explain how they systematically identified potential issues, such as overload or grounding faults, and the steps taken to resolve them.
- Sample Answer: "I identified a potential overload issue and adjusted the breaker ratings to match the load requirements. For grounding issues, I added additional grounding points to ensure safety."

Behavioral questions

Duration : 10 minutes/question

Tell me about a time when you had to collaborate with a cross-functional team to complete an engineering project. How did you ensure effective communication?
- Expected Answer: The candidate should emphasize clear communication, setting expectations, and resolving any conflicts.
- Sample Answer: "In my previous role, I worked closely with the mechanical and software teams on a product launch. We held weekly meetings to ensure alignment, and I regularly provided updates on the electrical design progress."
Describe a situation where you encountered a major problem in an electrical system. How did you approach solving it?
- Expected Answer: Look for a clear problem-solving approach, including identifying the root cause, troubleshooting, and implementing a solution.
- Sample Answer: "We experienced a sudden system failure in a factory line. I started by isolating the issue to the main power supply, then worked with the team to install a new breaker and ensured that all components were within safe operating limits."
How do you manage tight project deadlines, and what strategies do you use to prioritize tasks?
- Expected Answer: The candidate should describe time management strategies, prioritization techniques, and stress management in deadline-driven situations.
- Sample Answer: "I break the project into smaller tasks and prioritize the most critical components first. I also communicate with stakeholders early if any potential delays arise to manage expectations."

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
Technical Skills	"How did you design the power distribution system?"
Problem-Solving Ability	"How did you troubleshoot the issues in your design?"
Use of CAD Software	"Can you describe your experience using CAD for electrical design?"
Communication Skills	"Tell me about a time you collaborated with a cross-functional team."
Cultural Fit	"How do you handle working under tight deadlines?"
Adaptability	"Describe a time you had to change course in a project."

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.
