NO! There are companies that “want” Ross graduates. No question but many companies want educated students that can formulate ideas and communicate as part of a team
Most the other stuff you will learn when on the job. There are also a host of clubs etc at Michigan that are business like. I just gave you a few.
If going into business school is important to you then definitely apply to several. But many people have come out of Michigan’s LSA that become business CEOs also http://alumnus.alumni.umich.edu/notable-alumni/ list of companies recruiting from LSA would be a who’s who of companies. Can’t find a link but email the school and I am sure they have the information.
Keep in mind. Michigan’s a world Class university. Companies know the product they deliver.
