Wolfspeed Interview Process

The interview process at Wolfspeed is lengthy, and can be difficult for some perspective employees. The process usually starts with a phone screen from a recruiter, followed by a phone interview with the hiring manager. From there, candidates may be asked to do a presentation or fly in for an in person interview. The final step is typically an offer from the company.

1. What do you know about Wolfspeed?

This question is a great way to test your knowledge of the company and its products. When you prepare for this interview, make sure you read through the job description and familiarize yourself with Wolfspeed’s products and services.

17. Are you comfortable wearing protective gear such as goggles and hearing protection?

This question is a way for the interviewer to assess your comfort level with working in potentially dangerous environments. If you have experience wearing protective gear, describe how it helped you complete your work and what challenges you faced while using it.

Example: “I am very comfortable wearing goggles and hearing protection because I worked as an electrician for five years before applying for this position. During my time as an electrician, I was responsible for installing wiring in homes that were infested with rodents. The homeowner had requested that we use plastic covers over our shoes when entering their home so that we wouldn’t track any of the rodent droppings into their house. While wearing the protective gear, I was able to install all of the wiring without tracking any of the droppings into the home.”

18. Have you worked at a manufacturing facility before?

This question is a great way for the interviewer to learn more about your experience and how it relates to Wolfspeed.

I think if we implemented automated systems for these tasks, it would save time and allow employees to focus on more important aspects of their jobs.”

20. Would you be available to work overtime or weekends if needed?

This question is a common one for employers to ask because it helps them determine if you’re willing to work extra hours when they need you to. It’s important to be honest in your answer and let the employer know that you are flexible and will do what’s needed to get the job done.

Example: “I am available to work overtime or weekends as needed, however I prefer to keep my regular working hours during the week. If there was an emergency situation where I would have to work outside of my normal schedule, I would certainly do so.”
