Process
I was contacted because my resume was in a database for a conference.
The interview was in person, conducted in a booth during the conference.
Initially, they asked some questions about my resume.
They then asked why I wanted to work for Two Sigma. If you give a vague, general answer, they'll likely push for more detail.
Following that, they asked technical questions.
The interview lasted about an hour.
