Should my brakes squeek after the pads have been replaced?

I was advised by the dealer when my oil was changed at 46,000 miles that I shoul dhave my pads replaced at least by the next oil change. I hadn't noticed anything other than a minor squeal occasionally when stopping. I had the pads replaced and now there's a different type of squeek/squeal when i'm traveling at low speeds and applying the brakes (parking the car, stopping at the end of my driveway as I leave home). It doesn't seem to happen when i'm coming to a stop in normal driving, just at low speeds.
it seems like I had heard that that sometimes happens shortly after a brake job, but eventually goes away. Did they botch the brake job, or do I just need to "ride it out"?
