From my three interviews with the firm (oci, callback, offer) I found them to be very professional, yet very easy going with regard to work/life balance, choice of practice area, etc. I think it comes from the free market system and the flexibility it offers younger associates to work in a variety of areas. Apparently there is no face time requirement, as long as you get your work done. A number of associates said they never come into the office on a weekend (but of course, they put in 5-6 hours from home a few times each month).
All in all, I'm leaning towards taking the offer from them, regardless of the junk bond story on ATL, which seems to have been refuted in the comments section. Plus, I want to do lit anyway. Only a few days left to decide!
