You need to apply "brake grease" to the back of the brake pads where they contact the caliper assembly and the caliper piston. DO NOT put the "brake grease" on the braking surface !! The auto parts store will have little packs of the stuff usually near the counter. The little packs run about 99 cents a piece - one pack will easily do two wheels. It also helps to spray Brake Parts Cleaner on everything after the old shoes/pads have been removed - this removes the old brake dust that can lead to noise as well. Good Luck. Rotors get glazed. This is a HUGE cause of brake noise. Even taking some sandpaper and roughing up the front and back of them helps alot if you can't afford to have them turned on a brake lathe. Also, the caliper slides need greasing, and the edges of the brake pads where they set into the caliper need to be greased. If the brake pads have already been installed and driven on with glazed rotors, the pads will also need to be roughed up a little. Glazed rotors also increase stopping distance.
If the work was done recently, then the pads have not yet worn into the rotors. This can typically take up to 200kms to wear in properly.
If it is a Toyota, they do not know how to fix the squeaking brakes either. Even after replacing all the pads and machining the rotors and rear drums
buy good pads, and install and have rotors machined

Frozen brake caliper
Cheap metallic brake pads always squeal. It is recommended to turn the rotors and lube the slide pins. Is it four wheel disc? Make sure the noise is coming from the axle that the brakes were replaced. Do this; replace pads with ceramic brake pads, resurface or replace rotors, and lube all metal moving parts.
Have your brake pads checked. If the squeaking sound stop when you apply the brakes it may be your brake pad wear indicators rubbing the rotors to warn you to have your brake pads replaced. If you ignore it damage will result when the rotors and metal brake pad backing or rivets rub after the brake pad linings are worn away.
It must be the rear brakes at fault.
