Follow up.
From a reliable source (no, I won't name them), "they" have decided to spin up for a few weeks of interviews to replenish the pool since it is getting "shallow." Exactly how many weeks a few is remains to be determined. Sounds like the target is moving because they need new hires as much as they need to do upgrades.....
At any rate, I would imagine that replenishing the pool with June interviews means they are going to ramp back up bringing on new hires full speed in the fall. Of course that's my interpretation only. My contact didn't comment on that aspect.
He did say, after the June interviews (again, a few weeks) that they would throttle back, resuming interviews again in the fall (no date specified).
Just forwarding info guys/gals. Haven't seen any official update on the subject so standby for more.
Good luck!
