It means that you might get invited to a Phase I/II interview. If you already did Phase I/II, you might get invited back. HAL's HR likes to interview and reinterview. If your wondering why the guys on the Panal interview seem (sometimes) like they dont want to be there. Its because they are getting tired of recomending people, only to have the HR girl and the Psychologist hire someone else. Over 90 canadites got the letter mentioned above.

I know this because I have friends that work there. And I have interviewed there. After doing the interview, I got a class for United.
