Hi Flying Bear,
although I go against the notion of "incompetent CPs" raised above as a reasoning for their lack of response
I'm referring specifically to Ixixly's above post regarding a CP simply dumping the first half of the pile because he couldn't be bothered looking at them when I say that. I'm not referring to anyone I have known. As you say, they are generally busy and are not HR staff.
Best one I know of yet is from a mate who flew from Darwin to Melbourne for an interview and sim ride (obviously a larger operator). When he landed in Mel there was a message on his phone saying it was cancelled; no explanation, no re-schedule and no contact number! Incompetent. I would have followed up with a statement of demand from my solicitor personally.
Anyway, several months later he scored a gig with one of the majors and the original company that had earlier stood him up called to offer him another position! You can guess where he told them to jam it!
