Can anyone explain to me what this means:
Taken from NALP DIRECTORY FIRM: SKADDEN, ARPS, SLATE, MEAGHER & FLOM LLP - NEW YORK


Began work 2009:
Entry Level: 64 (64)
Post 3Ls: 2 (1)
2Ls: 102 (7)


What does the 1 mean after the 2?
What does the 7 mean after the 102.
What is the difference between "entry level" and post 3Ls.

Thanks

It's been a while, but I believe the number in paranthesis represents the number of people who spent time (usually a summer?) with the firm before. So in your list all of the entry level hires were with the firm before, but only 7 2L summer had been (makes sense, probably just a handful of returning 1L summers). I may be totally misremembering though.
