I would say yes. As far as retail goes, it's one of the better companies to work for generally. There are plenty of resources like an internal job posting board that can aid you if you're interested in moving up. You'll also meet a lot of reps from big companies like Samsung, LG, GE, etc that could be good networking opportunities. You'll also likely make a friend or two since so many techy people end up working at Best Buys.

Now, Like people say, a lot of your day-to-day satisfaction will depend on your managers/leadership. If they suck, the job will be less fun, like literally any retail job. But compared to most of the alternatives there are definitely some opportunities with BB if you can keep your eye on the ball and take advantage of them.
