1 phone interview plus 2 rounds of in person interviews. They also called my references. I met 12 Genentech employees through the process. High caliber individuals. Culture of "casual intensity" by as described by multiple folks. Also told that it was a feedback rich environment. Excellent employee development opportunities compared to other companies. Top of the line benefits (insurance, 401K, company shuttles, etc.). Work life balance is a concern based on what I could gather. Several employees said the expectations at Genentech are very high. Genentech is a great company!
