Meta Front-End Developer interview questions

Recruiter asked specific javascript trivia questions on first phone call, which I was not prepared for.

I applied online for the front end developer position and heard back the next day from a recruiter. We chatted over phone and she was very interested in my skills, so she gave me a coding challenge to complete. I was given an image, and asked to recreate the image in HTML/CSS/javascript with the functionality specified in an accompanying document. I finished it the same day it was given and gave them the code. Two days later the developers had reviewed my solution and asked to set up a Skype interview. It was an hour long interview where he asked about my experiences and we coded together online. They were two javascript coding puzzles (not exactly a clear representation of front end development skills). I got both of the puzzles working, but the next day they said they would not be moving forward with me.
