I aspire to become a venture architect or a strategy designer at the design/digital branch of MBB. And I have a few questions for you:

1. How does the start-up branch of MBB (BCG in particular) compared with the traditional consulting track in terms of career progression? What's the path like?

2. I am expecting an opportunity to work in a Business and Ecosystem Development role for a digital capability center at one of MBBs. I heard that the role will likely be a combination of consulting and the BD role itself. Any idea what people in the digital capability center works on? Are BD roles a good catalyst to switch to mainstream consulting afterward?

And questions about hiring process - 

3. I heard from HR I did well in the interview but I got stuck in the process (no response) after proposing my expected salary - for almost a month now. The HR said they are waiting for the line manager, what could it mean?
