Phone screen took about an hour. The usual they describe the company and role. Then, you describe your experience and how it fits the role. Overall, a well-paced and pleasant conversation.
The job description asked for a very wide range of experiences (including some that seemed more related to the backend implementation than the web/UI part). So, they ask for a lot and seem to want to get it all.
Also, though I have experience with similar tools/frameworks, I didn't have a lot of what they specifically were looking for (Marionette, etc.). And when discussing web security, I mentioned CORS and they thought I was saying "cores" (like CPU cores) and it took a while to sort that out and make sure they knew that I really was answering their question and not just flailing.
