SolarCity Javascript Engineer interview questions

The interview was a video chat over the course of about 45 minutes. Interviewer was in a cafe which I had never experienced before. I don't know if I'd recommend they do that again. Felt a tad bit unprofessional. We chatted about the role and the culture of the company. He then asked several "high-level JS questions" none of which felt particularly geared toward assessing a candidate's abilities. I was expecting questions more along the lines of "You're trying to build a new version of FizzBuzz with these new parameters. Explain how you'd do it." Instead I got "When would you use an anonymous function?" I get that that is a reasonable question but not one I felt was worthwhile... Anyway, I never heard anything back even after writing the interviewer a thank you email where he explicitly said I'd hear from HR. Yes I hear the silence. Loud and clear.
