I worked at Sheppard Mullin full-time (More than 5 years)
Wonderful team of attorneys and staff. It really feels like a family.
A small office sometimes means less support. Also, new office is beautiful but not convenient.
I applied through an employee referral. The process took 2 days. I interviewed at Sheppard Mullin (Palo Alto, CA) in June 2014.
On the phone then in person interview with office manager. Very informal, invited others into the interview to assess personality. Some quizzes were given to assess editing and problem solving skills.
I did not negotiate. Raises are given often so base pay was not a concern. Hours were good.
