How to Get a Marine Biology Internship. Many marine biology jobs are competitive, so getting a marine biology internship can help give you a leg up on the competition when you're applying for your first job (or even, another internship).
This means that schools are able to be much pickier about who they accept, and that even students with high test scores are being turned down for those with average scores and more real-world experience. Very few students make it into MBA programs with less than two years work experience.
Most full-time programs, however, require at least three years of post-undergraduate professional experience. If you are a recent college grad, you might want to consider an Early Career MBA program. Part-time programs typically prefer three years of work experience, although they will admit students with less.
