I applied online and was set up with the first round technical screen. The interviewers called me and asked me to navigate to a jsfiddle they had set up with some HTML code. It was a fairly simple search problem, but giving a JavaScript interview within jsfiddle seemed very awkward. Things I might do in my normal workflow, like writing a test or putting in console print statements, are difficult with all the noise in the console from jsfiddle. The two interviewers on the phone also seemed less than interested in what I was saying pretty much from the get-go. I got the correct answer, but it was my worst interview experience so far.

Depth-first search to find all elements in a DOM tree with a given class.
