Separate lady fingers or spread out 4 individual sponge cakes on a work surface. Using a pastry brush, liberally paint the cake with rum. Line small dessert cups or small glass bowls with cake. Top with heaping spoonfuls of prepared vanilla instant pudding, about 1/2 cup per dessert cup. Sprinkle sliced strawberries with sugar and toss to coat. Top dessert cups with sliced berries and sliced almonds and serve or refrigerate.
