He's rated on the 139. also he was not hired through Greystone or whoever and the money sounds OK. Not wonderful but OK.
They are talking to pilots rated on 412 and 139 apparently.
As far as not getting a reply to a cv this seems to be an industry standard now. Institutionalised bad manners I call it. CHC warns on their website they don't reply to CV's unless they want to hire you. No reply = no thanks.
