I applied through university. The process took 2 weeks. I interviewed at No Labels (New Haven, CT) in Feb 2014
Interview
I submitted my application through my university's database. They reached out to me via email and scheduled a phone interview. Lasted about 20-30minutes, and was very relaxed. They basically wanted to know why I was interested in their work, and how I saw it fitting into my academic choices. They asked my availability and let me know that they'd get back to me. Once I received my offer, I was assigned a partner in the firm to connect and advise me through the internship.
