The video interview was really tough because you aren't talking to an actual person, the questions are pre-recorded. Although they were all behavioral questions, not having someone else to respond to your answers is difficult.

You have to answer a few generic questions (either about the company or behavioral). After that, I got an email from a recruiter to set up a phone interview and it was also behavioral. My recruiter was very down to Earth and super easy to talk to. I got invited to come in the following week for final interviews. I had 5 back-to-back interviews and got a tour of the company. I think you have to have the personality traits to get an offer. Its a very young office and they want energetic people with lots of new ideas. Also, one of my 5 interviews was a case, but it was also very relaxed and my interviewer walked me through it, so as long as you have ideas, you will be able to finish it!
