Was referred by a friend in February, got an email for a phone interview in April which I did three days later (a Friday). Phone interview consisted of the following questions: background questions, explain your research, explain the equipment you used, explain a time something didn't work and what did you do to overcome it, tell me about a time you convinced your adviser about something, why do you want to work for Intel, did you ever modify a piece of equipment, and then was asked if I had any questions. I was told to always have questions on hand. I asked how they handled stress, their background, and how they liked the area. Phone interview lasted about an hour (which is what you should aim for to show you are interested in the position). I was told to wait a week for a decision, but was told 3 days later (Monday) that they would like to schedule an onsite interview 3 weeks later in early May. A company helps facilitate flights and hotel and they also mail a per diem card that you can use for meals while on the trip. About a weeks before the onsite I was emailed the agenda for the day and was asked to provide an abstract for the presentation on you are expected during an hour time slot. The onsite started at 7:50 am where I met with 15 different people, 12 of them interviewed me during a 1-1 session for 30 minutes, 3 of them took me out to lunch (which is still an interview!). Interviewers had a copy of the resume I gave to my friend for the referral and they asked me similar questions to the phone interview and also asked that I summarize my research. Alot of interviewers were genuinely curious to hear what I worked on and most were extremely nice. I did get the feeling that most were very tired and they each warned me about the amount of work the job entails. Some interviewers only asked 2-3 questions before they asked me if I had any questions for them so be prepared to ask a ton of questions to ensure you can keep the conversation going for the whole 30 minutes. My background is in ChemE but not semiconductor manufacturing which was no issue. The only ChemE technical questions that were asked were very easy that were related to my research so I knew it very well. Some interviewers were more critical in regards to my research and responses. I was told by my friend that sometimes they ask interviewers to be critical to see how the candidate responds to stress and criticism.The onsite ends with a facility. By then I was very tired but it was important to stay engaged. I was then escorted to the front door where I asked what the timeline would be for hearing back. The hiring manger responded to email him if I had not heard back within 2-3 weeks. I followed up after 3 weeks and was told they are still working on a decision. Received a call a month and 3 days later from the onsite saying they will be extending an offer. The next day I got the official email.
