    Write a function that determines the number of potential professional matches in a network by analyzing pairs of career interest codes, where a match occurs when the XOR of two professionals' interest codes results in an even number, indicating career compatibility. Each professional has a unique interest code, and the function should count all possible compatible pairs within the given network.
