What, exactly, would you like to do?
If you're going back to your company post-MBA, you're right, "rankings" really don't matter.
Try to find professors that are focused on the same type of marketing/field you're interested in. A school may be "#1 in Marketing" but I think there's a heavy focus on CPG. It looks like you're more interested in the retail side of things.
Thank you all for your time and advice, I would like to go back to the same company but I don't think they'll hold the position for me so I'll have to wait and see...
You are right faro I'm more interested in the retail side and I'm sure that with the right MBA I'll have a lot of chances of getting a good job when I come back.
Thanks again, I'll research the teachers and take a double look at Kellog as faro and sometimes kindly suggested.
Besides those two schools does any other name come across your minds?
