Development and exit opportunities for BCG knowledge analysts

Hi everyone,

I am currently interviewing for the knowledge analyst position at the knowledge team of one of BCG's practices. I am quite excited about the industry covered by the practice and about BCG, however, some of the details about the position are not clear to me and it's hard to find information about knowledge analyst positions so I decided to ask several questions here.

1. Is there any client facing or its strictly back-office research duties?

2. Is it possible to develop into a consultant, if yes, after what period?

3. Do knowledge analysts have similar exit opportunities as consultants (especially withing the covered industry)?

Thank you in advance!
