I tend to dismiss IB rankings out of the top of the top. Today, the Internet is your friend and so recruitment will be wider. It’s all about making contacts. IU and Miami of Ohio are both solid B-schools but I think people put them out like it’s the next tier - and I don’t think they are.
If you can handle an LAC (or if full tuition is appealing), the connections at a W&L will be much stronger (in my opinion).
Here’s a good link. It shows the top feeders but also adjusts for enrollment and you see a little bit of a change.
In the end, you have to be there four years - find the right school for you, not the right school for getting a job on Wall Street. Many from last year, for example, are still looking…and many firms are leaving…look for example, Alliance Bernstein is now in Nashville and UTK is on their radar.
Good luck.
