I applied online. The process took 6 weeks. I interviewed at Wolfspeed in Jan 2013
Interview
I don't remember exactly when I applied because I applied multiple places at that time. First, HR person emailed me that I would have a phone interview with a hiring manager for 30~45min. But it took only 25 min. Initially, the time for the interview was fixed but it was delayed multiple times. The questions were moderate. Most of them were behavior questions.
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
