I applied online. The process took 3 days. I interviewed at Kelley Drye (Washington, DC) in May 2011
Interview
It was a relatively easy interview with HR then with the attorney the position supported. They mostly wanted to see that I had relevant work experience and that my personality would mesh well with the attorney.
The interview process is fair. 2 to 3 interviews. Nice new offices in World Trade Center. Testing is also done and ask to meet with other assistants so you can make sure it's a good fit.
