entrepreneur to BCG

First time poster looking to see if there has been anyone in my situation or perhaps any advice. Management consultant prior to MBA Darden MBA completed in 2004 Co founded company from Darden Incubator 2008 co founded second company - secured financing and currently awaiting series A financing, but money is running out. Thinking of leaving due to uncertainty, family, looming college for kids...more stability. Classmate from Darden is a partner at BCG and thought I would be a good fit as an industry expert (food and bev and pharma). They have called me for an interview in 2 weeks.

Would love to hear from people who have traveled this path. Thanks in advance.
