First-hand accounts from people who interviewed at Wolfspeed.
Talent Acquisition Specialist
It was a long interview process - 4 interviews for a pretty junior job. They scheduled them all really fast, I had to take leave to go to the office. It was all in person. I was told I'd hear back the next week, but I followed up twice and never heard anything back about whether I got the job. I only found out through LinkedIn that someone else got it. Terrible practice from HR.

Equipment Engineer
The interview process started with a recruiter call, then a hiring manager chat, followed by panel interviews. The first two stages felt way too easy. Recruiters aren't usually a hurdle, but the hiring manager interview was surprisingly short and easy, less than 10 minutes total, and he seemed uninterested and barely looked at me. He only asked one generic question. The panel interviews were as expected, though lengthy. I was given a standard rejection email. My experience and resume made me overqualified. I thought I'd be a shoe-in. Friends on the inside mentioned that many openings are on hold until the factory ramps up, and they have many job openings for a factory that's not even close to being finished.

Software Quality Engineer
Applied for a job via Glassdoor and it was a good, detailed experience. Got contacted by the Talent Acquisition team quickly after applying, and they were professional and seemed really interested. They communicated well and kept me in the loop about what was next. The main part was a Zoom interview with two people, which was set up nicely. This virtual chat was a good chance to talk about what I can do and learn more about the job and how things work here.

Product Development Engineer
The interview process was decent overall, although the hiring manager wasn't great with communication regarding salary. It started with a standard HR call, then a 30-minute phone chat with the hiring manager where they discussed the company and asked some technical questions. The last stage was a tough panel interview with six people, which included a presentation of my research. They were focused on thermal analysis of SiC chips, so they asked a lot about Thermodynamics, Heat Transfer, and Materials. I got the offer after the final round. However, when I tried to negotiate salary, the hiring manager said he'd check with upper management. He never got back to me and instead interviewed other candidates. My offer was eventually rescinded because they found someone cheaper. It was disappointing, especially from a well-known company, but the people seemed great to work with, despite the miscommunication or budget issues.
