I applied online. I interviewed at Wolfspeed (Durham, NC) in Jun 2013
Interview
- First a phone screen with HR/recruiter
- Phone call with hiring manager and one other senior staff. There were a few technical questions asked along with some brainteasers.
- I was then flown out for an on-site interview.
- Onsite interview consisted of 7 interviewers (45 min slots) + HR/Recruiter as well as a 30 minute presentation
- The onsite interview was grueling and while some interviewers were friendly, others were downright hostile. I suspect this is part of their process to throw multiple personalities at you.
- The Fermi questions are too much. I know Google is famous for those, but even in my interviews with Google and other similar companies, they don't ask as many as Cree did.
- Lunch was great (Brazilian Churrascaria), but be careful not to overindulge (food coma). Also they kept grilling me with brainteasers at lunch.
- The technical questions were moderately challenging, but nothing really stuck out to me. I found the Fermi questions and one particular interviewer who challenged my hobbies aggressively to be the most annoying.
- Finally, being someone from California, they wanted to see I was interested in moving to NC. I asked for feedback after not receiving an offer and the enthusiasm to leave the Silicon Valley bubble was what resulted in the no-offer.

Interview
Long but fair. Started with an HR interview where I was asked standard questions as well as a time where I had to solve a technical problem and the steps I took to do so, then a 2nd phone interview with a manager who was friendly and polite. I was asked a combination of questions from what I am looking for in a job culturally,, behavioral questions, and some very straightforward technical questions pertaining to LEDs and semiconductors. I am preparing for my 3rd interview now and was told to expect 4 total before an offer. All the interviews are still over the phone, none in person. For the 3rd interview I have been asked to prepare a 30 minute presentation on research or a project I have completed and to expect 30 minutes of follow up questions from 3-4 R&D managers.

Question 1
Pertaining to an internship I'd done, I was asked to explain with some technical details a project I had listed on my resume.
Included an hour long presentation and a series of interviews with various departments and personnel within departments. Included three layers: phone interview, phone interview with presentation, and all day interview.

Interview
It was a phone interview which took at around 30 mins. First of all, starting with brief introduction of urself then the manager were mainly asking about my previous experience regards to its means of characterization, such as TEM, and SEM. Like how do you scan the sample? basic requirements for a TEM/SEM sample? or things like that.
