I got a call from HR on Friday. I didn't catch the call due I was busy. She asked me to return the call to the certain number. I called back on Monday, but no one answered the calls so I left voice mail. HR didn't get back to me back so when I called on Tuesday again. I don't know if I called too many calls (2 calls within Monday and 1 call on Tuesday). HR just cut my call when I called again around noon. It is pretty mean and weird.
