Applied online, got a phone call 7-10 days later asking to schedule a phone interview. Spoke the following week, basic HR phone screen, discussed education, industry experience and salary requirements as well as willingness to relocate. At the end of the phone interview, I was asked immediately to schedule the second round with a Principal Engineer and I was given their name. I did some research on LinkedIn before going in and I went through round 2. This time it was more technical, I was asked about "tools in my engineering toolbox" and I was asked how to approach a specific engineering problem and then if I had any questions. About a week later or so I was sent an email with an invitation to interview on site. I then had to complete a supplementary application and submit at least 8 references electronically and 3 on paper and send them the dates I would not be available. I booked my travel as soon as I could get a day off from work and I received the booking information. I was given 4 consecutive interviews. 1st interviewer was just below a VP in rank and it was to verify aptitude and assess if I fit into their culture; he wanted to check if I had done any sort of homework on the company and credo. The 2nd was an HR person there to ask some behavioral questions and assess my likelihood to relocate and assimilation. The 3rd was a project director, whom all engineers whether junior or principal, report to. She was there to assess my abilities and aptitude as well as assess if I would be an appropriate choice for the company and similar to her direct reports. The last interview were a pair of principal engineers who would more or less be mentors to junior engineers and this was the technical aspect. I was asked about my background, my research, my industry experience, my leadership potential and my rationale behind choosing J&J and specifically Ethicon. All the interviewers asked me why J&J and about my background. The last round also included an assessment of a technical nature, stress analysis with free body diagrams, failure analysis and risk analysis. In all rounds I was asked if I had any questions which you have to be prepared to ask for different levels of the company and different backgrounds. They will give you a bottle of water but there are no breaks unless you ask for a few minutes and I would highly recommend eating a light lunch before the 4 hour interview which ran slightly long each time. Be prepared for more advanced questions if you do not take control of the interview and ask for business cards at the end of each round, I forgot to but I sent my recruiter a thank you email that could be forwarded to the others.
