My brother works at MBNA. He had started out going to college, had no discipline, and went into the Air Force. His tour ended and he left. He applied to MBNA for their entry level job. Everybody at MBNA starts out telemarketing (they only call their own customers) even the college graduates. In fact, there are so many college graduates that it's tough to break in without a degree. Well, with his 4 years in the Air Force, they gave him a shot -- after 6 interviews! He's doing well now, better than he ever thought possible in the past.
I'm glad your brother's doing well. But: MBNA is a scumbag predatory company. Maybe they're great to their employees, but their customers are treated horribly. Google and see.
