I applied online 2 years ago but didn't hear back from a hiring manager until 8 months into my new position at a different company. I passed on the interviews but kept in contact with one of the hiring managers for when I am ready to move on. A year later the hiring manager recommends a position that opened up in their department, which I then applied to formally online. I talked to HR on the phone first who asked basic questions on what I am looking for at Genentech, and also answered any questions I had about the company and expectations on the process. HR was very friendly and were very transparent up front about the typical compensation expectations for this position. I then had a phone interview with the hiring manager that clarified more on what they were looking for and if this matched well with how I wanted to build my career. I was then one of three candidates invited on site for a day long interview, 8am-~4:30pm, 30min interviews with a total of 20 people in the department ranging from peer Research Associates to Director of the department. I had a few 1:1 interviews, but I also had 2:1/ 3:1/ 5:1 interviews throughout the day. All of the people I met were very friendly and understanding and did not throw any unreasonable questions at me. Most questions were about relevant experience and where I saw myself in 5 years. There were no theory questions on the formulas you learned in college but haven't touched on since (hiring manager emphasized that I did not need to study, just be myself). I also had plenty of opportunities to ask them of their experiences working there. You could tell that they took the process very seriously and made sure I was well-informed every step of the way.
