Comparatively hard, due to larger interlocking crystals and a higher density than most igneous/sedimentary rocks
Slate is a metamorphic rock that falls somewhere between a soft and hard rock. It is formed from the low-grade metamorphism of shale and is generally softer than granite or marble. It is commonly used for roofing, flooring, and as a decorative stone due to its ability to be split into thin sheets.
Schist is a medium-hard metamorphic rock that forms from the alteration of other rocks under high temperatures and pressures. It can range in hardness depending on the minerals present, but generally falls between 2.5 to 4 on the Mohs scale of hardness.
Gneiss is hard.
Generally speaking, when a geologist talks of "soft rocks" and "hard rocks" what he or she means is "sedimentary rocks" or "igneous and metamorphic rocks". Limestone is a sedimentary rock, and compared to most other rocks, is relatively soft. lol Different limestones have different hardnesses. Most "marbles" are actually hard limestones, because they have not experienced the high pressures and temperatures required for metamorphism.
Slate is a relatively soft metamorphic rock. It falls between the hardness of a soft rock, like talc, and a medium hardness rock, like marble. It is commonly used for roofing, flooring, and other construction purposes due to its durability and resistance to staining.
There are types of igneous rocks that are hard (eg granite) and others that are soft (eg volcanic ash). There are types of metamorphic rocks that are hard (eg gneiss) and others that are soft (eg marble). Thus "hardness" is not a characteristic that can be used to distinguish between the two.
Slate is a type of metamorphic rock that is generally hard and dense. It has a smooth, fine-grained texture and is often used in construction for things like roofing tiles and countertops.

Gneiss is hard.
Soapstone is a metamorphic rock composed of the mineral talc. Soapstone is a non-foliated metamorphic rock with a microcrystalline texture. It is very soft and can be easily scratched.

The rock you are referring to is talc, which is a soft metamorphic rock composed mainly of the mineral talc. Talc is known for its greasy or soapy feel and is commonly used in cosmetics and as a lubricant.
Igneous rock is generally hard rock because it forms from the solidification of molten magma below or at the Earth's surface, resulting in a crystalline structure that is dense and strong. However, the hardness can vary depending on the specific mineral composition and cooling history of the rock.
