I applied online. The process took 3 months. I interviewed at Fisch Sigler (Washington, DC) in Dec 2021
Interview
One screener with a partner, then a skill evaluation test (more or less like an intelligence measurement), a personality test, then finally one interview with another partner.
Each of the interviews takes around 30 mins, didn't get too much longer than that.
Interview questions [1]
Question 1
(1) What can you contribute to the firm?
(2) Why do you want to do patent litigation?
(3) Why DC?
(4) Prior work experience
