I interviewed with one of the companies on that list a few years back (noredink). They gave a timed hackerrank style coding question as round one (so I guess technically not a whiteboard). I passed that, then I had an interview with an actual person.
He asked me vague question, like what is architecture, I started to reply with what design tradeoffs I made on the app I was working on. He literally laughed at me, and said that is not architecture. I was shocked that someone would laugh at a candidate but said ok, what does architecture mean to you? He responded, I ask the questions here not you. I immediately ended the interview. Worst interview I have ever had. Every time I see that company brought up, I think back to that experience.
