I worked at Orrick full-time (More than a year)
Wonderful mentor who was not selfish with sharing the tricks of the paralegal trade. The attorneys are kind and willing to provide guidance for prospective law school applicants.
Most of the assistant work is document review and records management. Not much exposure to legal theory or compelling case work.
I applied online. The process took 1+ week. I interviewed at Orrick (Washington, DC) in June 2016.
I met with three lawyers from the group. The first round of two lawyers was interested in my background and interest in working at the firm. During the second round, right off the bat the partner asked me how I would feel if I have to perform her personal errands. I was perplexed. Was not sure whether she was serious, she was.
