I applied the first time was contacted by someone in HR saying they would like to move on to the next step. I then had a phone interview which I thought went well. Then, some time later, I received an email from HR saying that, since I did not accept their invitation for another interview, they have hired someone else. I was extremely confused, since I never received any such invitation. I replied, telling them this, and they simply replied that they "messed up" and "we are sorry. " Some time later I tried to give them another chance, so I applied again. This time they brought me in for an in-person interview. I thought it went very well, and I answered all of the questions well. I never got a call back or reply about the position. Very unprofessional.
