To whom?? It is rare that a candidate obtains email or other contact information of the interviewer. Companies have forgotten basic courtesy.

That sounds like a cop-out. How is it possible for a candidate not to already have that information? How would they otherwise know where to go and who to see?

In a lot of places, the candidate only has contact with one HR person or a secretary, before the interview. They have to get emails after they know the names of those who interviewed them.
