HELP - HR PROBLEM w/interview

Hey fellow Monkeys,

I have a problem and could use some sound advice. Was contacted from a major BB (MS/GS/JPM) last week to schedule interviews for IBD SA.

I replied with the times I was available, but since then no word from HR on my interviews. In addition, I followed up with HR stating that my schedule is lenient and I'm eager to participate in the interview but still.. nothing.

How do I go about this? Should I contact HR again saying that I'm available to interview or should I just let it go?

I don't have any experience in the Wall Street World, but these banks seems so organized in terms of recruiting that I don't know how they could contact about an interview and not follow up.

Any insight appreciated!
