I had a friend who worked in the group, so they were able to fast track my resume through to HR and get the process rolling more quickly than normal. In addition, I had a summer internship offer from this company 3 years earlier, so I was more of a "known" quantity to them. I received an email and call from HR to set-up the first phone screen, which focused on my overall background, interest in the company and pertinent expertise to the role. Because Genentech was in the midst of its merger talks with Roche, it took another month to schedule the next step, which was a phone screen with a hiring manager from the group I was interviewing with. At that point, I had a phone screen which focused mostly on technical skills pertinent to the role. After passing that screen, it took another month to schedule my full day of interviews in person at the company, where I met with about 6 people for 30-45 minute interviews. At the beginning of the day, I received a case study and had to put together an excel model and key slides to describe the situation and my recommendations in 90 minutes and then discuss with one of the interviewers over 30 minutes. My other interviews focused on my background experiences, interest in Genentech and ability to think strategically. Because I was not able to meet with the 2 heads of my group, they brought me back 2 weeks later to meet with them and then took another week before making me the offer. Overall, it took ~ 3 months from start to finish, but would probably take longer for others.
