It's largely a symptom of having mostly new grads do the interviewing, and favors new grads getting the positions, so around it goes. After a while you can get a feel for whether you're going to get anything out of the interview process other than a black hole (and probably lowball) offer and just abort the whole process before it starts. There's no point jumping blind from a good position into the unknown, especially given all the ??? are a bad omen.
