Similar situation here.
I applied for an IAT RET rate in October, was forwarded to employment division in late November, and have been “under review” since then with no forward movement on my app. Keep in mind this is a severely undermanned rate with fit/fill levels under 50%. In January I watched the offered recruitment bonus shoot up to >30k$. Nothing but silence from MSC.
No idea how these guys operate or what’s going on.
