ABL is still largely a 'family' business. It is small enough so everyone knows each other. Generally good teamwork between different teams. Still has an old school hierarchal feel about it.
Lots of social events, both firm-wide and team specific. Juniors typically work with their supervising partner, a number of senior associates and lawyers. Graduates are teamed up with a buddy who can assist with work flow and reviewing work. While the culture of each team in the firm in unique, my team is very social and cooperative.
Everyone is super welcoming, but there also isn't an expectation that everyone will necessarily want to get involved in the same way, so there is no pressure to "fit the norm" which is really nice.
