If you are an older MBA applicant, with seven or more years of work experience, you may want to consider the executive MBA. In general, the executive MBA program involves two years of weekend classes combined with the occasional week-long session. They can get away with less class time because their students already know enough about management to zip through the fundamental MBA coursework.
The Executive MBA programs tend to look more at the bigger picture management issues and give just a general management degree with no concentrations and little to no electives. Additionally, you are often put in a cohort group through the entire program. The advantage to this is that you develop strong relationships with your fellow students.
However, a disadvantage could be that it actually limits the number of contacts you will make. Unlike the full-time MBA programs, the Executive MBA programs do not normally include internships. They also often do not put the same emphasis on career services that full-time MBA programs do. This often makes them little less attractive options for career changers.
