Soak the dried rice noodles in a bowl of very warm (110F) water and soak until they're pliable but still rather firm, about 30 minutes. Drain in a colander - no need to pat dry. Meanwhile prep the rest of the ingredients.
In a small bowl, combine the fish sauce, sugar, soy sauce, hoisin sauce and chile-garlic sauce.
Once the noodles are drained, heat the oil in a large (12-inch) skillet or stir-fry pan over high heat until very hot.
Add the garlic, stir and immediately add the shrimp. Stir-fry until the shrimp turn pink and firm, 2 to 3 minutes.
Add the fish sauce mixture. Stir to mix for about 20 seconds, then add the chile slivers and the noodles. Stir-fry until the noodles are tender and the liquid is absorbed, 1 to 2 minutes. If the noodles are too firm, add 1 tablespoon of water and cook another minute.
Add the bean sprouts and stir-fry until they're slightly limp, 1 to 2 minutes. Transfer to a serving platter or individual plates, and garnish with the peanuts, cilantro and mint.
