public interface IFoo
{
    void Bar(int i, string j="");
}

public class Test: IFoo
{
    public void Bar(int i, string j="")
    {
        
    }
}

Question: in interface Ifoo is there a need to add optional parameter string j="" or one should go with string j? What is the best practice?

Yes. You need to add optional parameters to the interface – Jonathan Alfaro May 26 '21 at 14:35

"_What is the best practice?_" Depends whether you want to make the parameter optional or not when invoked via the interface. – Johnathan Barclay May 26 '21 at 14:40
