3.5 hours of interview. white board questions. They were 20 mins late to the interview (and we had 10 mins walk to another building), they were condescending at the end of the interview, and the interview stooped due to lack of time. very corporate organization (which is fine if this is something you look for)

First, talked with lead dev about me and project. Then, was invited to 3 hour interview live coding. Needed to implement explorer in react. Started with api discussion. I was making folder\file data structure in object for about half hour, then was asked to make test component that will take this data and they said it is enought.
