get a job

Are you serious? Your degree choice alone does not determine the likelihood of job placement. You have to have strong grades (which I'm assuming you assume yourself will have) as well as a demonstrated interest in working on wall st (internships, clubs, etc.). However, the most important thing is the job market itself. I would think someone with some smarts like you would know how unpredictable the future can be, if you've paid attention over the past three years. Earning a degree in Finance doesn't guarantee you anything. Actually, nothing is guaranteed. Are your chances improved? Yes.

Seeking a solid answer to such a vague and generic question is just a waste of time. If you do well, do some networking, etc, you will have chances, but it all depends on the other side of the equation...demand. I graduated last May with degrees in Finance and Real Estate and thought I was a perfect fit for a bank...over a year later and I'm just finishing my first week. Never take things for granted and never assume future possibilities based on historical outcomes.

The better question should be: What opportunities are likely to exist for a chemical engineering and business undergrad major at U of M? Then go from there. You need to understand everything that is "Wall St." and where you fit, thats more important than asking people the probability of random degree combinations increase the odds of working in the mythical firm called "Wall St."
