Initially an HR representative contacted me and asked me to fill out a long questionnaire with about 30 stereotypical job interview questions (greatest strengths, weaknesses, work habits, etc). I was given 3 days (over a weekend) to answer them and return the questionnaire via email. A few months later I was contacted by a manager and had a phone screen. The manager asked about my research experience and how I'd feel transitioning to a fast-paced manufacturing environment. The rest of the phone screen is discussing the job expectations, work schedule, etc. The 3rd step was a Skype interview with two managers where I was asked to give a 30 minute presentation on my graduate research. The managers were extremely curt and not very polite. Felt like they didn't want to be there. One of them was more tolerable than the other; he asked about big picture type stuff, what kind of applications do you see for the research, what are problems you solved, etc. The other manager felt like he was trying to purposefully trip me up; he kept asking questions about very particular details that were almost completely irrelevant to the subject. He was trying to find weaknesses in the presentation, and then acted kind of smug when he got to the point where you didn't know the answer to something. It felt like an attack, and it wasn't a pleasant experience at all. I was not selected for the last interview step, an on-site interview.

7-8 rounds of technical interview with different team members each lasting around 1-1:30 hrs. The interview was over 3 days and online. Then the HR interview and final interview with the hiring manager.
