Genentech Senior Manager interview questions

I interviewed for a position in the Market Analysis and Strategy Group. External candidates beware--it's an extremely long process, and you are often competing against internal candidates. I was ultimately told multiple internal candidates had applied, and I couldn't compete as they already knew the job. It starts with a call from an external agency doing phone screens, then the next call is with another external person (former employee). The third call (presumably before the in-person) is with someone from the Genentech team you're interviewing for. My first two calls went very well. For the third call (scheduled 5 weeks after my first call) , the interviewer was late, and immediately seemed disinterested. She cut off my response to the first question to say I was competing against internal candidates and there was essentially no chance they'd hire externally. I appreciated the interviewer's honestly and directness, but of course, I wish I hadn't invested so much time into a dead end. I understand the need to promote internally, however, it seems there is little proper communication between Genentech and their external hiring agencies. It also was a quite a long process to just let me know I was wasting my time from the start. I'm not sure what can be done to improve this, as it's likely the company has to check off a box to comply with regulations that internal candidates compete with external ones. However, external candidates need to know what they're going into.

The interview process began in a little ambiguous manner. Hiring manager's admin reached out via email (no introductory phone call, etc.). Hiring manager conducted the phone interview and quickly moved forward for in-person interview. I was super positive with the progress. The hiring manager appeared smart and to the point, so I decided to fly in for inperson interview. The interview was a day long one-to-one, but the unknown to me was that, they were interviewing me for 4 different positions. Two out of four roles completely unrelated to my experience and skills set. I had no prior intimation that I would be interviewed by managers in those two roles where my background didn't match atall. After several follow-ups 5 weeks later the hiring manager came back saying they hired an internal candidate for the role and asked if I was interested in one of the roles that never had a match. He advised that once I enter I can move into role of my choice! This didn't resonate with my expectations and career goals. I didn't move forward with the role.
