Sorry I know I posted this in 2 threads but didn't realize there was a specific thread for this question...

In my experience they don't have to call you back in general because usually you aren't technically an employee until u pass the DT. So...typically not receiving a call means either one of two things: (1) HR is lazy/inefficient/they are doing mass hirings and calling back a bunch of peeps at a time (Best Buy took a month n a half after meh DT to call me back when I first started working there) or (2) you failed and they don't feel the obligation to call you back.
One thing you can do is call em and ask if you have a first day scheduled yet.
