I applied through a recruiter. I interviewed at Arcadia Data in Feb 2019
Interview
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.
I applied through a recruiter. The process took 1 day. I interviewed at Arcadia Data (San Mateo, CA) in Mar 2015
Interview
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.
