Super impressive interview. They had a great take home section that tests your knowledge of ruby and classes. I would say its an easy-medium level difficulty and you get 2.5 hours to complete. They give you a gift card as well for attempting that section of the interview. The last round is a panel interview split up into three sections - one technical challenge, a database question, and behavioral.
