Here is a tip for those getting invitations to interview. May not work for everyone but did for me. I received my invitation email on a Friday, 25 July. When I called them, I was given a date of 1 Oct which seemed to be the norm. I asked if there was a Standby list that I could be added to in case someone dropped out or cancelled and told them that that I would like an interview as early as possible. I was called the following Thursday, told there was a cancellation on Monday 4 Aug, and was asked if I would be interested in coming in for the interview.
I am not sure if a standby list actually exists or if the person I set my interview date with just remembered that I wanted to come in ASAP. It was a rough 4 days getting everything in line for the interview, but the outcome was very positive. I received a CJO and was called 2 weeks later with an Indoc date.
I was invited to interview on 25 July and will be starting indoc on Monday. Bumped me up the seniority list at least 200 from where I would have been otherwise. Give it a shot guys. It couldn't hurt.
