BB, I think that most large banks actively recruit at each of the top 16 schools (ending with Cornell/UCLA). From my understanding, about 70+% of US citizens going out for IB from that subset of schools get an offer (it may be lower tier or middle market, etc., but an offer nontheless).
Ross is definitely a member of this club, the difference between them and Darden/Duke/Tuck/Yale is that instead of 10-15% going into banking, about 8% do. That's the same % as Texas, and the lower number is slightly self perpetuating and mostly self selection at Ross. All of this is to say--you no longer need a "top 10" MBA for better-than-even odds of getting IB, but rather top 16ish and some recruiting even extends fairly well into the certain top 20ish (from UNC all the way to Gtown and Vandy).
While McCombs is not part of that top 16 group, they place EXTREMELY well in Houston for energy banking. OP, if you have no geographic preference, would this be appealing?
The biggest wildcard for you is the international aspect. I have heard this is tougher but I have no idea about numbers. Have you been able to reach out to any students in your position at these schools?
