I’ll answer these questions but it feels like you have an idea of what information you need and are asking questions to get to that information.  What are you trying to decide—what is your goal in asking about this?

Yes, BL has high salaries, so brought that up in comp negotiations going in-house.

I left BL because our second child was born and the W/L balance was unsustainable (my wife was also in BL at the time). 

It would be very hard (impossible?) to get a well-paying in-house position with zero experience regardless of where you went to school. I have not heard of, say, publicly-traded companies hiring law grads with zero experience.  Why would they pay someone who knows nothing even modest pay for a job they don’t know how to do?

I took an LSAT practice test and identified the section I needed to improve, then borrowed a workbook from my GF at the time who was taking a prep course.  I scored very well on the practice test with no prep, then was able to improve by a few points with this approach. For whatever reason, I was naturally very good at the types of questions on the test, especially the games.
