Wolfspeed R D Process Development Engineer interview questions

Phone interview followed by a Skype interview/presentation to a group. The Skype interview was bizarre, the group didn't introduce themselves, and their camera was turned off, so they could see me but I couldn't see them. I gave a 30 minute talk and then answered questions for 30 minutes. Hands down the most unpleasant interview experience I have had to date. Declined onsite interview.
