I applied through college or university. I interviewed at Wolfspeed
Interview
Applied online through campus recruiting website by submitting resume. Was sent and filled out a 25 questionnaire. They emailed me asking to set up a phone interview for the next day. They were about 15 minutes late in calling, said the process would take half an hour but was closer to an hour Talked about my resume but asked a lot of why questions. Continually asking to explain your explanation. You have to really know the technical details to what you're talking about.
