I may the pessimist here, but I don’t believe I personally would turn down a job simply based on the type of company it labels itself as. In this day and age, especially for people fresh out of college, landing a job in any field, even engineering, is taxing. This is made even more difficult if students never undertook any internships, co-ops, etc. relating to their field while as a student. In my case, I would take a job no matter the type of corporation it is. I would rather base my application on the company’s mission, ethics, and opportunities offered. I think looking at the type of company a business is comes into play when you are a venture capitalist and you’re searching where to invest your money, which 90% would be to C-corps. Otherwise, although looking at the type of company a business is can give you an idea of what that business is all about, for engineering I don’t believe it applies as much as it would for a business person.
