I ended up talking to a recruiter for the company, knowing nothing about it, at a career fair my school ran. He was very kind, and very enthusiastic about his job. I gave him my resume, and he got excited looking at some key points on my resume that he felt would be a good fit for one of the intern positions at his location. Asked for his contact info, and was referred to company email (only because he had ran out of business cards for the day). I did not hear about anything for 2-3 weeks following the career fair, after having emailed the company site. I looked online and applied to as many intern positions as I qualified for / was interested in. There, I put down the recruiter's name, hoping to grab his attention. From there, he responded to me within a couple weeks, and I was then scheduled to have an on-site interview. I had no phone interview, which surprised me. I was told later that talking to the reps in person at the career fair counted as an "initial candidate scan." I was at the company site (Marlborough, MA) for about 2-3 hours, talking to 4 people for 30 minutes each. I ended up talking to employees there for so long that the main recruiter came back to talk to me for even longer about the position. I asked about how quickly they would be able to respond, and they said that they needed to screen the rest of the candidates before making a decision. From then on, it took about a week to receive an offer, though I know that they were in a rush to extend offers before too late (which was good for my personal anxiety). A week of waiting felt so long! From there onwards, it was very easy. The company was so accommodating, and I felt that I had been given far more than what I expected.

Process took a long time (roughly 3.5 months), but once the interview process started it was quick (2 weeks). Had interviews with 4 senior engineers and Director. First was an HR call and later a phone interview with director. an onsite interviews was scheduled which lasted for roughly 4 hours. Overall experience was good.

First step was 30-minute in-person interview. This stage was a 'cattle call", with several people scheduled in 30-minute blocks. Received a call-back after 2-3 weeks for in-person interview. Met with hiring manager, peers (2), director, and HR. Was told decision would be made within 1 week. Two weeks later HR called to set up a phone interview with hiring manager and peer to ask additional questions. At time of meeting one of the persons was unavailable. Hiring manager asked a few additional questions. Set up another phone interview for the following week. Hiring manager was unable to make this meeting. HR stepped in, cancelled the phone interview and sent an offer letter. Offer was low for someone with an advanced degree and several years of experience. I counter-offered, and was told the hiring manager would call.The peer who had interviewed me previously was now the hiring manager (I assume he was promoted). He called, said the offer was non-negotiable, that the job did not require an advanced degree (job posting stated explicitly that advanced degree was preferred).
