Prepare for a technical interview with CFA studying?

So let’s say you’re going to have a phone discussion with someone at an investment bank. It may or may not be an interview, but you want to err on the side of caution. Let’s say technical questions will be asked and you’re studying for L2.

To kill two birds with one stone, what topic would you spend your time studying from now until the interview? If I had to guess I would say Equity first, then Corporate Finance.

Thoughts?

I’d spend my time studying the Investment Banking study question PDFs online. They normally seem geared around DCF calculations and the like.
