The interview involved first an in-person screening (now there is a phone screen), then a half day interview with the rest of the UI engineering team where I had a couple 1-on-1 interviews with people on the team and was able to get a sense for the team dynamics.

Standard software engineering technical interview and then onsite with white boarding. Also given a coding task at the onsite. Asked to write JS CSS and Python. No crazy algorithms, or anything like that just practical stuff.
