I did two 30 minute phone interviews. They asked mostly behavioral questions, inquiries on what you did in your previous jobs, and some brain teaser like questions. They wanted to learn about your thinking process.

Following an online application, there was an initial phone interview followed by multiple in person interviews at their offices in New York City, NY. The initial interview was 30 minutes long, and the in person interviews can very in length, but they usually take up the entire day collectively.
