What am I expected to know walking into SA/FT IB O&G Interviews ?

Hey all,

I got lucky with a connection and ended up with a phone call this week with a MD in an Oil & Gas Investment Bank. If I'm lucky and get a more formal interview, what would a MM/boutique investment bank focused exclusively on O&G expect from someone walking into a round of FT IB Analyst interviews?

How about if you are going for SA positions (currently debating delaying graduation a semester, so curious)? I have no IB/Finance internship, and what I have isn't helping me much.

I have gotten things like how things flow through accounting statments, DFC, ratios, stock pitches, current events, basic term definitions, etc but just curious on the industry specific, smaller firms.

Thanks for your help,

Forrest
