Bentley is considered a regional MBA brand. If you want to stay in New England after school you can likely find a job in the area with an MBA from Bentley. However, just because a company hires Bentley grads it does not mean that they hire them for the jobs/functions you are interested in. Your best bet would be to research Bentley's placement stats in the types of companies and job roles you're looking for. Usually schools have a link on their website for you to contact them with questions. Just email them and ask about their resources and placement in your area of interest. They should be able to put you in touch with current students and alums who can tell you how they've fared.
If you can get a higher GMAT score (700+) and maybe an additional year of work experience you would have a shot at some Top 20 schools.
