The interview was a take-home coding challenge which focused on practicality and knowledge of JavaScript web development. It was split into 2 parts, sorting / processing data, and displaying the data visually. I was given 3-4 days to do the challenge, and on the day of the interview I was asked to explain my code in detail. The interviewers were all very friendly and created a casual environment so that I would be comfortable. There were also some behavioral questions at the end; so be prepared to talk about you past experiences and contributions in detail.
