The test consisted of questions regarding HTML5, CSS and plain JS. Parts of it were about writing some code (pen&paper), others about writing what a console.log would print out for some code. I found one of the questions to be incomprehensible (with regard to what they actually wanted from me), but there was no one to ask for a clarification. General topics were: - AJAX requests - HTML5 storage and cookies - CSS selectors' priorities about JS: - closures - hoisting - scoping - stuff related to dynamic typing and its consequences That's how much I remember, there were probably a few topics more. The 30 minutes were supposed to put a pressure on the candidate, even the test itself contained a remark about getting as much as possible done. Some of the questions contained really specific edge cases you'd normally avoid to code that way. The technical guy actually didn't ask a single question with regard to the test, so there wasn't any way to discuss it. It was a general conversation about my experience and tooling. Absolutely no feedback was given. The HR lady asked the typical HR questions, verified my proficiency in English and financial expectations. The only positive thing is that I got some (but not a lot of) informations about the work they do, how they are doing it etc.
