Two 45 min behavioral questions with current employees on the team. While not specific to the principles they were certainly implied. This was the 1st round with a 2nd round on site with 4 more behavioral rounds.

A friend that works at Lab126 forwarded my resume to HR and about 3 weeks later they emailed to set up a phone interview that happened about a week after that. The phone interview was about 10 minutes and very professional but a bit frustrating as understandably the HR person did not understand the technical aspects of the position.
