I was advanced to the Superday round where I was interviewed 2-1 for three interviews. Interviewers were all generally nice and easy to talk to, which made the process a little less stressful. They barely introduced themselves though and left no time at the end for questions (including asking for their email addresses), so I had no way to contact them or follow up. When I reached out to general recruiting for that information, I was ignored. I received no follow-up communication whatsoever, so was just left hanging for a very long time.
