I am just a bit confused, so:
Is determining eigenvalues of hermitian matrix basically the same as how we determine eigenvalues of real-number matrices?

The characteristic polynomial of a hermitian matrix has all coefficients real. You can write a companion matrix from these coefficients. The companion matrix is a real matrix.
