The whole process was very fast and fun.
Had two video-conferences: First was to critique an App (had Yelp) with 2 designers, second to walk another designer through a project on my portfolio.
Onsite interview started out with a portfolio presentation for around 6 or 7 designers. Then I had 1-1 with them to discuss my work, experience and also space to ask my own questions. I also had to critique another app and do a whiteboard design exercise with 2 designers. Fun!
The experience was awesome and kinda of made me realize how important it is to know what questions to ask. Those questions can probably tell a lot about you, as much as your answers to their questions.
