But definitely opaque in an atmosphere where they need you more than you need them.
I can understand if they don't want to give the hiring manager's name until the interview because some people are crazy on linkedin. BUT, they should definitely be able to give you better details about the interview.
But usually I wont waste my time past the first call if they can't put a name on the hiring manager.
