Here's my two cents...
Class of 16 on Jan 22. Aready filled.
Class of 16 Feb 19. Calls going out now.
Class of 16 in March. this should drain a lot of the pool.
No other classes planned after that- they are looking at numbers, waiting for the bean counters, possibly the seat bid. Of course, there will be a lot of hiring after March. But the numbers aren't set yet.
