I applied online. The process took 2 weeks. I interviewed at Wolfspeed in Jul 2014
Interview
Questionnaire with 25 questions to get to know you and your background. Then phone interview, then day long skype interview where you present something you have done and have 8 people grill you about it. Then an on site interview. Did not make it to the on site.
Normal tell me about yourself, why do you want to work here, problem solving example, technical question specific to the area you interview for. HR phone screen, manager phone screen then in person interview on site
Multiple interview rounds, multiple interviews with heads of different departments as the last round. Interview process started with a phone recruiter, followed by a hiring manager, the Hiring Manager's manager, and then a final round with all the heads of the departments independently (4-5)
Interview questions [1]
Question 1
Technical Questions like about SPC, Troubleshooting tools, Working with multiple cross-functional teams, high-volume manufacturing environment.
First was a 15 minute phone call with HR followed up by a 45 minute interview with hiring manager. One more round of interviews after this if I had gotten through
