US Postal Service PSE Sales & Service/Distribution Associate interview questions

I applied online and got an email to take an online assessment. I passed and got an email to schedule a test date for test 473. I got an 86.6 and got an interview 2 weeks later. Didn't take interview yet.

I actually haven't been interviewed yet. I applied 3/17/2016 and took the online assessment the same day, then immediately after got an email inviting me to schedule a proctored assessment, which I took 3/24. I scored an 86.7 and 3/28 I received emails for drug tests and a background check which I responded to immediately. I took my drug test 3/29 and since then my status hasn't changed from Pre- Hire list, but I haven't received a much anticipated e-mail to do an interview yet. I called GIS and they informed me that both my drug test results and background check results were sent to the post office 3/29. So now I'm just not so patiently waiting.
