An interface encompasses all the signals utilized in the design. A virtual interface acts as a bridge between the SystemVerilog design and the testbench, connecting the static design world with the dynamic testbench environment. Since the DUT remains static and persists throughout the entire simulation, while testbench components are dynamically created and destroyed, virtual interfaces are employed to establish and maintain this connection seamlessly.

RTL and TB are connected through interface signals. Interface is nothing but bundle of signals. While RTL is module based (i.e. static) and will ultimately be made into hardware, testbench on the other side is class based and therefore dynamic in nature. Virtual interface basically gives a pointer of actual interface to testbench components.
