Nothing particularly interesting here. Pretty standard questions about REST, webdev, which javascript libraries to use. Some small talk here and there. Interviewers seemed knowledgeable enough. Didn't really talk or get to know them though.
Multi-round waste of time: after outlining the number of rounds, they spring another round at the last minute to rule you out, despite making it seem like you performed well. Of course zero explanation at that point.
I applied online. The process took 1 day. I interviewed at Passport (Charlotte, NC) in Sept 2019
Interview
First round Technical Interview. If you pass that you get to go to another interview that is more difficult and in person. The first part of the process has you do video conferences with people you may be working with.
