Be prepared to talk about how your experience relates to the role. Be flexible when it comes to interviewing schedules as new teams need flexibility. The team did want to move my interview back to 3 days which would have made me the last interview, and I simply told them that I could not change my dates at the last minute. The recruiter if it is a contract position will meet you, and will prep you. Everything salary or benefits do not talk with Genentech. They are the client and cannot really answer those questions. For an all day interview, remember where the bathroom is, bring an iPad or book to read in between and arrive early. Make sure you have your government ID. Also bring a snack. They will provide water and lunch for you. I sat alone in the same interview room all day and was happy each time I met someone. Leave door slightly open after you have a lunch--do not get anything with onions!
