Computerized Assessments & Learning interview questions

In person interview with the team. A few questions on background, some light technical questions. They asked if I looked at the code challenge. Apparently they never sent it to me. After the interview I received the code challenge. It was vague and contradictory. I worked on it listing assumptions I had to make so that it would work. When I went in for the second interview. I asked what a successful answer would look like and they admitted they didn't actually know. As I was walking through the code, I had to explain some basic features of the language (.call()). A week later, they asked for references and they contacted them. A week after that, they asked that I do the exact same code challenge with a few modifications. I sent it to them and then. . . nothing. No phone call. No email. Guess they weren't interested, but it was the rudest experience I've ever had in a professional setting.

First two rounds were on the phone. First was behavioral and second was technical screening. Final interview was on site and it was all technical. Some basic coding questions and questions on web frameworks.
