I think you don't have an answer because they don't know what to tell you . . . . . . really! The Q400's are late, there are rumours about the Govt (recently politically realigned) not honouring their promises re finance for the new airframes ? ? certainly they have not arrived. Q400 colleagues are doing virtually no flying, even if Base Training of newbees was taking place only 1 week ago.
In short, there is some plan in the background (or perhaps the problem is No plan? or a plan that has been foiled ? ) and the HR Dept / Flt ops etc are as baffled as anyone else.
Something is brewing, and no-one knows if they will like how it tastes. I seriously wouldn't plan on an employment offer before May, but that could of course change as quickly as the wind.
